I have a 98 ls and right now I have stock exhaust with universal muffler.I am just trying to find out opinion's as far as hourse power gains and sound qaulity.I plan to go turbo soon but still would like to know wich brand's worked best for all of you.Thanx.

 

search apexi-hks- rsr just a few

 

Witch one do you have?

 

If you plan on going turbo, then no point in buying an exhaust now. a 3 inch exhuast is optimal for the average turbo set-up but for a stock ls it will kill whatever power you have now. so wait until your turbo then i would recommend thermal turbo cat-back, i have this exhaust and it very nice deep tone but it pretty loud ( im running 3 inch downpipe straight to the exhaust no cat or resonator). also heard great thing about Kteller exhaust system.
