If I replace the restrictive factory resonators with 3 inch race bullets will I really notice a difference noise wise? What about if I just replace the resonators with exhaust pipe? My car has LT headers, O/R x-pipe, and American Thunder mufflers.

What is your goal, different sound or more power?

Agree with deranged, need some more personal input for this question to have an accurate answer!

Just to open the exhaust up since it gets down to 2 inches where the resonators are. I'm quite happy with how it sounds now. Doesn't make sense to have a full exhaust if I'm bottling it up at the back.

Should be fine then. I am not sure how much the tone will change, but I do know it will relieve some back pressure and let you breathe a hell of a lot better in the high rpms! Keep us posted!

I've heard that some people have only gained 2 to 3 hp with a resonator delete and up to 7 hp from changing the over axle pipe. Don't know much about the bullets but I'm sure they are better than the stock resonators. Go for it and let us know how it turns out.
