just bought supersprint exhaust, the guy who sold it to me says its gonna add about 4-6hp and about the same torqe,will I be able to feel the difference.

If it actually add 4-6hp, yes. I think mostly you will notice the cool new sound. But if you don't like it, I'll be more than happy to take it off your hands :naughty:

Dopeman, i just bought a supersprint for my 328is and it arrived the other day. still waiting to install it though. i think my brother and i might do it ourselves bc they quoted me $80+ for installation. let me know how much they charge you.

ya, so i it cost me $70(cdn) to get it installed i called a few other places and they were all sayn 80+ ,but it was a good fit,so if u wanted to illini you could do it yourself as for the sound, it pretty much sounds the same until you get to about 4500+rpm thats when the fun starts:bigthumb:
