Rogue Engineering E30 M3 Exhaust
Get rid of your old and restricting E30 M3 Exhaust and replace it with a free flowing Rogue Engineering E30 M3 Axle Back Exhaust.  It is made out of full stainless steel and unlike most exhausts for the E30 M3 it is straight bolt on.  This Rogue Engineering E30 M3 Exhaust gives you not only improved power gains, and throttle response but makes your M3 sound like a true BMW M vehicle.

What about Performance?
Rogue Engineering intentionally designed this exhaust to have tubing diameters that are 23% larger than current aftermarket choices on the market for a number of reasons. 

  • With many of Rogue Engineering customers taking their E30 M3s to the track, more flow at WOT only benefits those that live at redline
  • Once the stock S14s require rebuilding, 2.5L conversions are becoming more popular, which require more flow
  • The ultimate conversion, dropping in S50, S52s and S54 engines, require much more exhaust flow capacity than the OEM dimensions

For the M Car that Started it All
Some will argue that the E30 M3 was not BMW's first M car and they are right.  However, here at Rogue Engineering, the E30 M3 is a car we still enjoy and love today (with stock S14s and transplants).  As these cars start to become scarce, we noticed that pricing on parts in the aftermarket industry continue to increase.  We feel that this was the perfect time to introduce a product for this cult car.
