318ti Stromung Cat Back Exhaust ­ After significant dyno and racetrack testing, Stromung became our exhaust of choice. Stromung, is carefully tuned to offer enhanced performance without compromise. All other exhaust systems we tested traded low-end torque for peak horsepower or vice versa.

All Stromung systems are light weight and are made here in the USA. They produce a moderate, throaty sound­- not so loud as to drown out your Harmon Kardon stereo and are accented with round stainless exhaust tips. Standard construction is stainless steel, but some systems are available in aluminized metal for cost savings.  For E30 and E36 models including M3, Z3, and M Coupe/Roadster. Call for availability for other models. 

**This exhaust has been discontinued...HOWEVER, if there is a group of 10+ people willing to purchase we can have more produced.**
