Dumped or duals
 

I have a true dual flowmaster 40 series running out of the back, ive gotten alot of compliments on it, but i want to know if i should 1)dump it after the axle or 2)dump it and cut the cats. i want to get a little bit more of an intimidating sound, like a growl, but idk if the cats getting cut off will do the trick

dump it after the axle. don't gut the cats

ive heard that taking the cats off though increases horsepower?

it can, but the hemi likes a little bit of backpressure.

After the axle.. I had an AT3030XL dumped after the rear axle and it sounded amazing

Duals. I've personally never liked the way anything dumped sounds.

Agreed. Duals back, x pipe before mufflers to even out air flow, duals out. With 12 inch or 15 inch echo tips. Do that with two super 44 flow master mufflers. The outcome is a deep, menacing sound

I'm running dual 3 inch into cherry bomb xtreme single in single out, mine dump before the axel, I move alot more air than a hemi but its got a real nice rumble down low, and screams up high. No cats either.

if you dump it and not use echo tips you get a deeper sound only drawback to dumping it is more reverb in the cab i personally don't like how tailpipe exhuasts have more of a echo'y sound

Well if your wanting horsepower lose the flow master for starters and get a straight thru muffler like a magma flow.. I personally don't like tips out the back besides on lofted trucks with like 6 inch diesel tip. But each to his own. I'm putting a roll pan on in future to elimanate my tips
