Right now I have a stock G92 dual cat muffler with a dynomax muffler. Here's a clip http://media.putfile.com/Z28-Engine-Rev

it sounds ok but doesn't have that good F-body V8 sound I want. What do you think I could do to achieve a better sound? Remove cats? Bigger pipe with cats removed, or is it the muffler itself? I dont want to dump a bunch of money in it but should I just get a new muffler plus all others? I'm thinking if I remove the cats it'll help a lot. I have a small pin hole in my piping so I might as well upgrade that.

What size would you recommend?

 

I had dynomax system a while ago and hated how it sounded. I now have hooker cat back and love it. Its a 3 inch system with dual 2 1/2 inch tailpipes

 

I like the way hookers sound with longtube headers. My flowmaster force II catback has a nice tone when you get on it. If I had to choose, I would go with hooker for affordability, and sound.

 

I like my Flowmaster American Thunder cat-back on my red '91.
VERY DEEP sounding!
Not too loud.
Factory manifolds, custom y-pipe, catco converter, 3" American Thunder.


My white '91 has the Force II.
Has a nice idle, but is raspy revving up and has a ring to it.
SLP headers, no cats, Force II (yuck)

 

I actually kind of like that sound. I have flowmaster 40 series and I think it just sounds too popular I guess, everyone's got that tone.

 

Does it whistle? Mine did and I fixed it by sizing up the mis match in the y-joints for the chrome tips.
