For a head turning sound change without the glitz of an aftermarket system; the OEM Exhaust Mod is for you.

335i exhaust systems normally have internal open baffles, chambers, and secondary resonators inside them to absorb sound and reduce volume.

Each system is carefully cut open and new bypass tubes are welded inside. The bypass tubes improve exhaust flow and increase sound volume. The canisters are then re-packed and welded shut for leak free OEM like performance. You end up with a stock looking exhaust system that performs like a race exhaust.

"This was a simple, quick and great sounding mod! I made an 8am appointment and they had the car on the rack and working on it by 8:03. These guys are great! They had a unit already complete. Walked me through the process and what it looked like. I was out the door in 1 hour. The car sounds great. With the windows down you can enjoy the sounds and with the windows up and the exhaust flapper engaged (if that's your thing) you can't tell the difference between stock. There is Zero drone. Alan and David answered all my questions and were extremely expeditious. Very happy and a wonderful first impression. Will be going back soon for the intake port cleaning. "
