I must admit I was getting a little jaded after 4 months and 3,500 miles with my M3. The newness was wearing off. I must say, this Eisenmann exhaust has changed that--it's what should have come from the factory! The sound level and tone is PERFECT, IMO. It's deeper and throatier, but not at all obnoxious or droning. Unfortunately it may impact my fuel mileage, since I now like to hear the car rev more; but, even at lower revs it sounds great!
List price is $2,839. Nate at IND (distributor for Midwest & West) can direct you to retailers. Construction & fit seem first rate. Tip size: 76mm stock, 83 mm Eisenmann (20 % larger in area). Weight: 43.7# stock; 46.3# Eisenmann.
Pacific Motorsports in Portland did the installation. They welded the pipes to the unit reather than using the supplied clamps because they thought the clamps resulted in a little leakage.
I'm in love with my new again car!
