If there is a minimal torque loss, its on low end and its not noticable, power still stays the same, in fact, my car sounds like beast and I always get compliments everywhere of how it sounds. For a 135i muffler you will obviously need a y pipe, same concept. Every bmw performance exhaust comes with a resonator delete, much better for the sound. Secondary cats, yes, I would delete that as well too, highly recommend it, my car is already loud enough tho  |
perhaps its good that I did not do the PE mod then.. I got a magnaflow muffler. here are clips of my exhaust note:
