Which one???

Which cobination produces more power!

1. Stock manifold, 3" y pipe, high flow cats and a loud mouth or

2. Stock manifold, 3" y pipe, high flow cats and no muffler at all ?

Me and a friend are debating this issue! Thanks for your help!

The loudmouth doesn't have a muffler, its has a resonator which is completely hollow. I don't think there would be any difference between a LM cat back or just pipes.

I agree with Kataklysm

Thanks! I guess neither of us was right! lol
