Pipe Size.

[GMhunter93]

On my 5.7l I have a single 2" ID pipe, with a cheap ass CB turbo Tube. Am I giving my motor enough pipe to breath with or do i need to switch to a larger pipe or duals? I just had the new exhaust put on last summer so I'm kinda hoping that I don't need a new system. Thanks guys.

I have a 3" pipe with a 2 1/4 glasspack and it dont sound to good im thinking about doing away with the glasspack and just dump it after the section pipe.2" sounds very small
