loudest muffler

ok guys i need some good opinions. i have an '89
firebird formula with a bone stock 350 tpi. whats the loudest
muffler available. this means no combination with headers, missing or gutted cats, im talking with the stock dual cat setup.
ive got a couple brands that i know- flowmaster 80, dynomax race magnum, hooker aero chamber, slp loudmouth.

Your going to want a straight through muffler. Such as magnaflow or a dynomax bullet.

out of those choices, the SLP LM is by FAR the loudest.

However a system that is just as loud, but has WAYYYYY better tone and costs a LOT less, would be the dynomax bullet muffler.

Straight through designs are the loudest. Click on Hear me! in my sig to hear my bullet muffler.
