The Borla catback exhaust system is a nice way to improve the look, sound, and performance of your 95-99 BMW E36 M3. Every Borla exhaust is made in the USA using the highest grade T-304 stainless steel and is backed by Borla's Million-Mile Warranty. But that's not why you want this catback on your M3; you want it because it will give your E36 M3 a little more grunt and a little more growl. The subtle, dual, 76mm rolled, polished tips add just a hint of flash over the stock exhaust's tips.
