deepest, loudest exhaust at IDLE?
Ok, if you had long tube headers, going into a 2.25" Y-pipe, into a 3" center pipe, then back out into a 2.25" Y-pipe into the mufflers on a 350 TPI, what would you think is the deepest sounding idling exhaust?
Muffler elims are out (inspection won't pass)
So, what makes that offshore powerboat idle sound? Flowmaster 40's, super 40's? Mangaflows? Give me ideas. I don't care about WOT, just an exhaust in the idle-3500RPM range.
Just checking opinions.

I would think SLP's Resonator would be the most loudest/deepest at idle but really raspy at WOT and then Dynomax Bullet Mufflers would come second, they are a lot less raspy at WOT.

My flowmaster is pretty deep at idle. The 80 series tend to have a hollow sound at idle, but it has a lot of bass to it that rattles frames and sets of car alarms 
I like it 
(Sound clip in sig).
Cartman, your car sounds sick :hail:
