hello i need someone to give me some advice on what to do with my 6 cylinder camaro exhaust. i have a flowmaster muffler and resignator on. But at high rpms it sounds like complete ****!!! i need some advice. some body help!!!

Tony this needs to get in a tech section where others might have more input. This 'interior' section is more for seats, dash, consoles etc.
Welcome and good luck.

What diameter pipe and where are the muffler and resonator located? Where does the tailpipe exit?

And what is ****e? Are you talking about a resonant noise inside the car? I had a 2.5" Flowmaster on a 6 cylinder in my pickup years ago. If I remember right it did sound rather annoying but it was a pickup so I just dealt.
