new to ls1 world... need guidence
as far as exhaust, there's a never ending line of exhaust systems and muffler combinations for these cars. i'de suggest going to LS1sounds.com and they have a ton of exhaust clips. Long tube headers and an Off road Y-pipe (no cats) sounds great as long as you have some sort of muffler. something along the lines of an SLP loudmouth sounds good with stock manifolds and cats, anything less and the loudmouth is obnoxious.
Stock rockers are fine on these cars. a good bang for the buck mod is to throw a gear in these cars. Cams make hefty power in an LS1 as well! maybe someone else will chime in for some more help!
that's my $0.02!
