Eisenmann Sport Exhaust BMW Z4M $1300.00 + shipping costs
I picked these up from Goodspeed in Scottsdale this week. The exhaust has approximately 300 miles on it and is virtually brand new with very little sign of use. This exhaust retails for $2192.00.
The exhaust is louder and has a much deeper tone than factory, and the fitment is perfect. The quad 83mm tips fill the notches in the bumper. Eisenmann also mounted the tips low on the muffler, so nothing hangs below the bumper.
This is the best looking exhausts I have installed on a Z4M, but I decided to stay with the obnoxiously loud RPI’s.
