Lol ok Mr P. I yield to your 35 years experience in the exhaust lab.. I'm not as smart as you, I got no problems admitting it. That said, for the rest of us who want huffs in the stockish location, the bigger the muffler (internally), the better. Helps dissipate heat & gas expansion.

I would never run a 2 1/2" tail pipe on anything with 600 hp, that is just silly. Oh, curious, how do you know it is 600 hp?

Yea,I know,,,even with a 4 inch going into 3.5 there is ALOT of backpressure.I bought the material to install cut outs after the "X" and before the mufflers.
HEMI-ITIS has no cure. My condition is fully BLOWN!!

I read a test where s dude with a big inch Hemi powered street based car had dual 3.5" out of his collectors to a pair of under-the-seat mufflers then into 3.5" tailpipes and he hated the volume of the exhaust. So he dynod it on the chassis dyno to get a baseline. He then proceeded to go from 3" to 2.5" to 2" tailpipes out to the rear bum;per and recorded the differences in HP/TQ. The end result was a loss of a total of 6 HP from the 3.5" tailpipes to the 2" tailpipes yet the sound was WAY quieter and comfortable for him. Make of it what ya'all will

Don't the FAST guys only run a 2 1/2 system... Of course, I'm sure their build is centered around that restriction..

I'm gonna ask a dumb question just so I can get it out of my head, have any of you tried the Flowmaster B-body tailpipes on a Duster? Can they be made to fit or is it a completely different deal? I want the TTI tailpipes but I'm gonna have to really be in the mood to do it as they are around $300 with shipping.

I'm sure with some mods they can fit.. lineup the hump area(over the axle) and a B-body being longer you do a couple of cuts to make them fit.... I dont remember the hump being any taller or shorter
