What is the quietest bullet style muffler (straight through) muffler out their? Price doesn't matter, I just want to know which will quiet a sytem down the best.

 

i ran a 23.5" long bullet from summit or jegs (generic brand i think) on one of my setups...it was decent. much more sound material than the 16" or 18" units.

if you have a little more room i'd look into the magnaflow 4x9 straight thru mufflers. i have a pair on my cammed LS1 with TDs...and it made a HUGE difference.
