Anyone tried &/or seen these on other e30 M3s? Any noticeable performance gain or is the car just louder?
Performance improvement is my goal without having an obtrusively loud exhaust note. I used to run these on my VW GTI's back in college, but I have not found anything other than Euro headers for the e30 M3.
The car has 48k mileage, Dinan chip, UUC short shifter, & cross-drilled rotors. Otherwise all is stock. New muffler was put on car shortly before I purchased, so I don't see the need to spend $ on a new TriFlow/SuperSprint/Remus muffler from cat back just yet...
Comments & suggestions appreciated.
Supersprint sells a center section with just resonators not cat.
I can't say that my car has much more power with it, maybe it does, but I switched from a Dinan chip to a Conforti (JC) chip and it made a noticeable difference.
BTW a co-worker today confirmed it for me, my car shoots flames when I'm upshifting. ;-) Part of the thrills of removing the cats and a cold engine that is running a tad rich.
