im thinking of spending some more money on my car and either getting some spintech prostreets to replace my single chambers or a mac straight shot. i heard the spintechs make good power and also the mac cai does too. help me out a little
spintechs are loud as crap... I have a friend with a 99 cobra with a mac o/r h and weld in spintechs.. loud!! didnt sound too bad though, I love the idle sound.
Hes already got flowmaster 1 chambers, so my guess is its already loud as ****
Go with the CAI, you won't pickup any more power from swapping mufflers. You car is already probably nice and loud, so go with the straight shot. Its new on the market and I haven't heard anyone thats NOT happy with it, although the exact gains are still debateable
