For not only aural enhancement via the elimination of the central collector\/resonator, but also weight savings and simplicity. The stock single-to-dual pipe setup has been abandoned in favor of an enlarged, straight, unrestricted, and freer flowing single pipe system. This pathway feeds into a Helmholtz equipped muffler that limits frequencies associated with drone, as well as assists in altering the overall tone of the setup to deliver the signature low Dinan rumble. The no-nonsense design allows versatility in volume levels with the retained factory valve functionality. Go from refined when cruising (low RPM’s) to rowdy when in it (high RPM’s), with ease. Or better yet, pair the system with an exhaust valve remote and have full control of elevating or reducing the sound! When open, the system behaves as a straight pipe solution that promotes maximum flow and volume for an exhilarating and forceful chorus. When the valve is closed however, exhaust gases are wholly redirected through the muffler and emit more tempered vocals acceptable for even the most sensitive ears. It is the perfect blend of civility when cruising or the full spectrum of auditory delight when in the throttle.  No matter the situation, the Dinan valved cat-back exhaust system is the answer for the discerning enthusiast looking for sound without sacrifice.\u003c\/p\u003e\n\u003ch4\u003eFeatures \u0026amp; Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFactory-like fitment with included mounting hardware and valve componentry for both pre-LCI and LCI compatibility\u003c\/li\u003e\n\u003cli\u003eQuad 3.75-inch (95mm) double-walled, black ceramic coated, clamp-on tips with laser engraved Dinan logo\u003c\/li\u003e\n\u003cli\u003eFactory valve functionality retained; refined or rowdy from the same exhaust\u003c\/li\u003e\n\u003cli\u003e7-pounds lighter than the stock system (60-pounds vs. Dinan: 53-pounds)\u003c\/li\u003e\n\u003cli\u003eEnjoyably louder, sportier sound w\/ a delightful octave drop\u003c\/li\u003e\n\u003cli\u003eDrone abatement technologies used to reduce cabin resonance\u003c\/li\u003e\n\u003cli\u003eLarger diameter piping for increased flow (83mm vs. 80mm)\u003c\/li\u003e\n\u003cli\u003eFactory resonator\/collector removed for increased volume\u003c\/li\u003e\n\u003cli\u003eDirect bolt-on w\/ no cutting or welding required\u003c\/li\u003e\n\u003cli\u003eMaximum gains of +6 HP and +5 lb-ft of torque\u003c\/li\u003e\n\u003cli\u003e100% 304 Stainless Steel construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eDownloads \u0026amp; Resources\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/b84e402d16514cf5669a2688d5bea3b7.PDF\" target=\"_blank\" rel=\"noopener\"\u003eInstallation Instructions (PDF)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":62971897839697,"sku":"dnnD660-0099-BLK","price":1862.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1079\/2688\/0337\/files\/82e99c85da50201772899b2049c01be2L.jpg?v=1792181974"},{"product_id":"dinan-20-24-bmw-m340i-m440i-g20-g22-g23-g26-free-flow-axleback-exhaust-system-black-tips-d660-0085-blk","title":"Dinan 20-24 BMW M340i\/M440i (G20\/G22\/G23\/G26) Free Flow Axleback Exhaust System - Black Tips - D660-0085-BLK","description":"\u003cp\u003eThe use of quad tips also presented some additional challenges and fostered some innovation to the already visually impressive system constructed entirely of TIG welded and brushed T304 stainless steel.

Unlike the previous generation where cabin sound\/drone was largely unchanged between the sedan and the coupe, that was not the case with the G8x chassis'. This caused countless iterations to be attempted in the quest for a common system that not only sounded superb externally but one that also didn't introduce an overbearing internal cabin drone on either body type. The result is a system we are confident will be coveted by all for years to come. To achieve desired sound volume and tone worthy of the G8x M3\/M4 the tubing was enlarged to 76mm (vs 70mm stock) to allow freer flow, and reduce backpressure, throughout the entirety of the system. The larger piping gives way to multiple pathways as it nears the rear of the vehicle -- the choice of which is utilized determined by the factory exhaust valves which are retained. When valves are closed, flow is directed into the Dinan muffler, where absorption and reactive technologies are used, and exit out the two inner tips.  This limits noise during low-speed driving and produces a more subdued, albeit deeper, and agreeable note.

With a nearly perfect symmetrical design, the raw muffler and pipe routing are pleasing to the eye even when the matching proportions are only partially visible after install. The piping culminates into four massive 114mm (4.5\") tips that fill up the previously spacious factory cut out in the valance without appearing to be oversized and unnatural. The imposing tips utilize a new tip design with an inverted clamp neck. The new style allows for two very important things to happen. The first is the ability to have a longer tip sleeve length without sacrificing real estate for a clamp neck thus allowing larger tips even when there is limited straight pipe to clamp on to. Secondly, the interior clamp neck means that the clamp itself is almost completely hidden from view for an unblemished install. Dinan has retained its signature straight cut tip design, safeguarding its unique and elegant styling position amongst a crowded marketplace full of angle cuts.

Fabricated from brushed 100% T304 stainless steel, TIG welded and free of hydroformed pipe, the upgraded system is a marked improvement from its predecessor - both in terms of material\/construction as well as in overall looks. For weight savings and simplicity, the stock single to dual pipe setup has been abandoned in favor of an enlarged, free flowing single pipe system. This pathway feeds into a muffler that limits frequencies associated with drone, as well as assists in altering the overall tone of the setup to deliver the signature low Dinan rumble. The no-nonsense design allows shocking versatility in sound levels when paired with features, like valves, often associated with more fanciful alternatives.

For not only aural enhancement via the elimination of the central collector\/resonator, but also weight savings and simplicity. The stock single-to-dual pipe setup has been abandoned in favor of an enlarged, straight, unrestricted, and freer flowing single pipe system. This pathway feeds into a Helmholtz equipped muffler that limits frequencies associated with drone, as well as assists in altering the overall tone of the setup to deliver the signature low Dinan rumble. The no-nonsense design allows versatility in volume levels with the retained factory valve functionality. Go from refined when cruising (low RPM’s) to rowdy when in it (high RPM’s), with ease. Or better yet, pair the system with an exhaust valve remote and have full control of elevating or reducing the sound! When open, the system behaves as a straight pipe solution that promotes maximum flow and volume for an exhilarating and forceful chorus. When the valve is closed however, exhaust gases are wholly redirected through the muffler and emit more tempered vocals acceptable for even the most sensitive ears. It is the perfect blend of civility when cruising or the full spectrum of auditory delight when in the throttle.  No matter the situation, the Dinan valved cat-back exhaust system is the answer for the discerning enthusiast looking for sound without sacrifice.\u003c\/p\u003e\n\u003ch4\u003eFeatures \u0026amp; Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eQuad 3.75-inch (95mm) double-walled, polished (or black ceramic coated) clamp-on tips with laser engraved Dinan logo\u003c\/li\u003e\n\u003cli\u003eFactory-like fitment with included mounting hardware and valve componentry for both pre-LCI and LCI compatibility\u003c\/li\u003e\n\u003cli\u003eFactory valve functionality retained; refined or rowdy from the same exhaust\u003c\/li\u003e\n\u003cli\u003e7-pounds lighter than the stock system (60-pounds vs. Dinan: 53-pounds)\u003c\/li\u003e\n\u003cli\u003eEnjoyably louder, sportier sound w\/ a delightful octave drop\u003c\/li\u003e\n\u003cli\u003eDrone abatement technologies used to reduce cabin resonance\u003c\/li\u003e\n\u003cli\u003eLarger diameter piping for increased flow (83mm vs. 80mm)\u003c\/li\u003e\n\u003cli\u003eFactory resonator\/collector removed for increased volume\u003c\/li\u003e\n\u003cli\u003eDirect bolt-on w\/ no cutting or welding required\u003c\/li\u003e\n\u003cli\u003eMaximum gains of +6 HP and +5 lb-ft of torque\u003c\/li\u003e\n\u003cli\u003e100% 304 Stainless Steel construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eDownloads \u0026amp; Resources\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/b84e402d16514cf5669a2688d5bea3b7.PDF\" target=\"_blank\" rel=\"noopener\"\u003eInstallation Instructions (PDF)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":62971899445329,"sku":"dnnD660-0099","price":1862.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1079\/2688\/0337\/files\/a4a4029b39fb48a36d7ec69617dee422L.jpg?v=1792181982"},{"product_id":"dinan-17-21-bmw-230i-f22-free-flow-axleback-exhaust-system-polished-tips-d660-0076","title":"Dinan 17-21 BMW 230i (F22) Free Flow Axleback Exhaust System - Polished Tips - D660-0076","description":"\u003cp\u003eDinan engineers designed the BMW F22 230i exhaust to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration.

The piping has also enlarged to allow freer flow and bring the tone even deeper yet. While these things all make the system a respectable representation of a Dinan M exhaust, what really sets the system apart is the incorporation of an 'X' in place of the factory resonator. Not only does the overall volume increase, but the crossover allows for a refined and smoothened exhaust note complete with a perfect mix of exotic undertones and raw aggression.

When valves are closed, flow is directed into the Dinan muffler, where absorption and reactive technologies are used, and exit out the two inner tips.  This limits noise during low-speed driving and produces a more subdued, albeit deeper, and agreeable note. However, when the valves are open during high-load conditions the bulk of the gases bypass the muffler altogether for a near straight pipe design and maximum aural enjoyment to be achieved.

The Cool Tips also avoid the possibility of a nasty burn while loading items in the trunk. Employing the principle of rarefaction, the design features an inner and outer tip with a vent at the base. When a positive pressure wave travels to the end of an open pipe and is ultimately expelled into the atmosphere, a rarefaction or momentary drop in the density of the surrounding air is created behind it. This momentary drop in the density of the air surrounding the pipe's exit creates a vacuum, pulling the air from the surrounding area to fill the void.

This is partly courtesy of the retained computer-controlled exhaust valves that limit noise during low-speed driving and open fully during high-load conditions to allow free flow. Like all Dinan exhausts, our M550i Free Flow Axle-Back Exhaust is engineered to reduce low-RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone. In fact, on the G30 M550i equipped with a Dinan exhaust, you will be astounded at how eerily quiet it is in the cabin. That is quickly changed however when exiting the vehicle and being witness to the sporty luxury sedan revving its stout V8 engine with the exhaust valves wide open.

The Cool Tips also avoid the possibility of a nasty burn while loading items in the trunk. Employing the principle of rarefaction, the design features an inner and outer tip with a vent at the base. When a positive pressure wave travels to the end of an open pipe and is ultimately expelled into the atmosphere, a rarefaction or momentary drop in the density of the surrounding air is created behind it. This momentary drop in the density of the air surrounding the pipe's exit creates a vacuum, pulling the air from the surrounding area to fill the void.
