Hey peeps. I was wondering if anybody knew which was the better exhaust system between the SLP Loud Mouth exhaust, or the best known, Borla Cat Back exhaust. The Car they would be going on would be a 4th gen. Ls1 Camaro SS (99-02). I have not gotten it yet, but those are the years I'm looking for. And for when I do, I would like to know which is the better exhaust system. I know Loud Mouth is much cheaper... please help...
