FIRST WAVE OF MODS! E9x
Jumping into the performance upgrading head first! Ordered MS pulleys, MS stage 1 intake, Challenge x pipe street, Challenge slip on exhaust, and a few cosmetic stuff for sheer ascetics. Dumped about 4k+ on these goodies and my question is, am I being penny wise and dollar foolish not going with the extra $300+ for the MS stage 2 vs. MS stage 1? Personally, from what i read, I doubt I'm gonna feel the difference. And also, I cannot seem to find a vid of full Challenge exhaust (street x pipe w/ slip on rear)? Does anyone have this setup? Am I gonna need a tune?? It never ends, LoL!!! Thx...
