performance chevy muffler

[HALLETT BOY]

Anybody know which performance muffler works good on a 6.0L Chevy pick up ?
Had a Flowmaster but took it off due to extreme resonance in the cab..

Hallet,
I Built a stroker 383 for my old suburban. Went with 3" exhaust into Flowmaster 3 chamber and had the "Extreme resonance" in the cabin you have. I took it back and they swapped out to a flowmaster "RV" muffler. It is 4 chamber. The sound outside, performance etc was the same. But way quiter inside. I loved the sound after that. You might try it.

I have the 6.0L Crewcab Chevy 2500HD with a flow master but also had a four chamber installed, I think it was their 70's series. Even with a supercharger installed the flowmaster is working well, not too restrictive and no resonance issues in the cab.
