you just want louder exhaust, but 135 and z4 are much louder then 335s.
i mean, thats just my opinion. i dont think exhausts are really worth it(500-2500). I run a muffler delete, cheap, saves weight, and sounds great to me. drones but people say even PE drones (which drones immensely less then a muffler delete)
id save some cash and play with your stock exhaust before spending the money. the money for exhausts are really paying for how well an exhausts sounds without any drone. which is hard because im sure that if people think PE drone alot, you'll hate everything else.
i dont think an exhaust will be the deal breaker in a race either. you really get minimal hp gains. Though a great sounding car is alot more enjoyable.
