Ultimate Racing 335i COUPE Cat-Back Exhaust with Dyno!

Hey guys,

We've been getting countless emails, and calls for our E92 335i Coupe version of our 335i cat-back exhaust. The wait is now over. Again, here are some key features of the exhaust (which is actually very similar to our E90 335i Sedan cat-back).

- Full 304 Stainless Steel Construction
- Equal Length Piping
- Twin Polished Stainless Steel Mufflers
- Polished Stainless Steel Muffler Tips (Available in rolled, and single wall)
- Stainless Steel X-Pipe
- Stainless Steel Clamps
- TIG Welded
- 100% Bolt-On with ZERO modifications
- Great sound with ZERO rasp!
- 23 lbs Weight Savings (55 lbs vs 78 lbs stock) *This still has to be verified on the coupe





Here are the underbody shots that most of you have already seen from the Sedan thread. The Coupe is very similar.









Again, you'll notice that the exhaust is designed to keep the pipes equal length, while retaining maximum flow. The muffler tips are angled with the same contour of the rear bumper. Each piece is TIG welded to perfection.

Here are the dyno results. It is important to keep note that no other modifications were done to this car. No tuning, just our cat-back exhaust installed. Try to look beyond peak numbers, and notice the power it has made throughout the powerband.





We should have some updated videos soon. In the meantime, anyone that hasn't heard this exhaust can hear it on our automatic Sedan. The sound is identical.
