exhaust system for 04 tiburon

[summer14]

What is a better exhaust system that adds more HP, greddy, apexi, or borla?

i could be wrong, but i think generally cat back exhausts, are going to put out around the same numbers. the header is usually where the big power differences are.

Yeah I think he's right. On my Accent,the cat back did nothing i could HONESTLY notice but did sound cool,when i got my RPW 4-1 hpc coated extractors,i definately did notice a nice gain(and it got a helluva lot louder too)
