Pit+Paddock E91 M3 GTS Build Episode 7: Akrapovič Exhaust and DSS Driveshaft

As we’ve highlighted on several occasions already, a complete build is seldom just about the visuals. What’s under the skin - or in this case, underneath our wagon’s body - is just as important in our mission. A mission is exactly what this build has been so far. We’ve taken the vocation to create the ultimate E91 wagon, one that respectfully nods notes of inspiration toward the undisputed king of the E9X lineage: the E92 M3 GTS.
There was significant groundwork that needed to be laid for us to accomplish this mission properly. But once that was painstakingly completed - thanks to our project partner Precision Sport Industries (PSI) - the momentum of our project continued to build. In what felt like a matter of days, the E91 transformed, and the heart, which was substantially revised by Carbahn, arrived for transplant. A set of Bilstein 2-way Clubsport coilovers, a suite of suspension components from SPL, a Trophy big brake kit from Stoptech, and a boatload full of additional upgrades kept all capable hands on deck at PSI. Its hard work and dedication to this effort cannot be understated. There are very few shops that would be able to stomach a project like this with as much fortitude as they have shown so far.
The back-patting has been admittedly truncated for the sake of progress, however. There is still plenty to accomplish en route to its SEMA debut, and this round of upgrades brings us back underneath the car for a couple of notable weight-loss modifications from Akrapovič and Driveshaft Shop.

Loving this build. It's truly something special. Wondering though why the driveshaft you guys are using is not listed on their website. I hope they'll release it soon?

[@pitandpaddock]

Thank you so much! The DCT-specific DSS driveshaft was made specifically for this car. As a custom application, I'd reach out to DSS directly to get one for yours.

Was the Akrapovic exhaudt a custom job for this build?

[@pitandpaddock]

The Akrapovic exhaust is technically for an E90 M3, so there was custom work to fit the E9X M3's mounting brackets, etc. underneath the chassis and re-work the bumper to accept the quad pipes. Well worth the effort I think!

@@pitandpaddock I thought it was only for the E92 and not E90. Which was my hold up on getting it.
