alright guys ive decided to just go buy a new muffler. i got a magnaflow on it now and it has to much interior noise. it makes everything on the inside vibrate at about 2500 and up. anybody got any recommendations on a good flowing muffler that is pretty quiet? thanks

 

FloPro HD

A few guys on this site (including myself) have these and love them. No resonance at all and flow good.

 

go with borla, sounds good at WOT and no resonance inside.....

 

How is it exiting? I have the small 4x9x11 Magnaflow, and I don't get any resonance. At 2500 rpm mines wisper quiet. Just a quiet humm of the mudders is all I hear with the windows up and the radio down. Mine exits in front of the pass, rear tire.
I was gona get the Borla, might try it when I get my LT's

 

stock exit. edelbrock headers, no cats single 3in inlet with 2.75 outlet. very loud.

 

I have the biggest magnaflow and its stock quiet, I have cats though so might be a lil louder but not a bad thing cuz right now its silent, If I want loud I open my cut out

 

I have the Flo Pro HD as well. It's the 2503 version- dual in, single 3" out. Slight rumble to around 2000 RPM w/ no interior resonance at any RPM.
