OVERVIEW
Looking to elevate the external acoustics of your G8x but want to upgrade in stages and/or not break the bank? The Dinan Middle Exhaust for the G80 M3 is and G82/G83 M4 introduces a more aggressive tone and an increase in volume over the stock system while retaining the factory muffler at a budget friendly price point. Should the desire for more arise however, it can easily be paired with the matching Dinan axle back exhaust for further aural enhancement and a more aggressive growl. It is a union that boasts a bold, yet sophisticated, exhaust note that neither can fully achieve on their own. This middle exhaust itself removes the hydro-formed factory center section from the secondary catalysts back to the axle back, including both resonators, and replaces it with larger 3-inch T304 stainless steel tubing for freer flowing capabilities. In place of the forward factory resonator, Dinan incorporates a beautifully crafted X-pipe made from mandrel-bent tubing for minimum restriction, unlike stamped X-pipes which are commonplace in the market. This hand-made 'X' is not only the focal point of the system in terms of aesthetics but also the star when it comes to the effects on the sound. Promoting even flow to both banks of tips, the 'X' removes unwanted nuances in sound caused by uneven exhaust flow that is present in the stock system. Along with the inherent benefit of increased volume by removal of the resonators, the Dinan X-Pipe for the G8x M3/M4 produces a louder, smoother, and fuller exhaust note that will deliver smiles time and time again.
Features:
- Smoother, louder and sportier sound
- 76mm (3-inch) tubing replaces stock 70mm (2.75-inch) tubing for free flow
- Deletes resonators between the secondary catalysts and rear muffler for increased volume
- Includes X-pipe crossover made from mandrel bent tubing for minimum restriction
- 5-pounds lighter than the stock mid-section (Stock: 22-pounds vs. Dinan: 17-pounds)
- 100% 304 stainless steel construction
- Factory-like fitment with included mounting hardware

Solid quality and good price
Size: 10 sqft
I bought this for my custom built camper van and it’s been great so far. For $24, the amount of coverage you get is totally fair, and I’ll probably grab a second box to finish everything. It’s easy to install with just scissors and something to press it down, and making quick cardboard templates really helps for tight spots. The adhesive is insanely strong, so once it sticks, it’s not going anywhere (just don’t let it stick to itself). Keep in mind this is sound deadening, not full soundproofing, but even with partial coverage I can already hear a difference in reduced road noise and vibrations. I’m using this as a base layer and plan to add soundproofing on top, and so far I’m really happy with how it’s turning out.

It's a job but totally worth it
Size: 36 sqft
Pack a lunch when you tackle this project boys.. its a doozy!! Month in going great so far definetly did what I purchased it to do. 2000 chevy with two p3 10s every bass drop sounded like an old firebird with loose trunk bolts. Threw this on the back walls floor underneath the speaker and the doors.. all that energy is now in the cab with me instead of getting lost in rattling metal!! Love it!!! Left a few pieces outside after I was done rained like hell on them so water doesnt hurt this stuff at all or direct sunlight in south mississippi.. good stuff pick this up and make them systems thud instead of rattle!!! You wont regret it!! I didn't!!

This works very well to put down road noise. The difference was immediate in my van. I was shocked it made such a difference.

Reasonably priced sound deadening
Size: 18 sqft
Easy to cut with a carpet knife. I used a heatgun to make it stickier and more moldable. The foil isn't so thick that you risk cutting yourself like some Dynamat variants.

Sticky so don’t let it touch you or each other but it comes off and works fine.
