The 2659 is also very fast. It has less bottom end than the nova pipes, but more top end. They all work great with the RBM3.
The 2660 gets the most runtime out of these 3 pipes. The 2652 makes slightly more power.
Thanks for that Murnan!! Ill keep that info till I get the '11 M3 Tuned from you in a few months!!
Still learning to drive better and setup cars, so the tuned would be good enough for me, otherwise can you modify the Tuned version into the Modified version easily? Or are the timings done differently that doesn't let you crossover between Tuned and Modified?
