Great video to help newbies like me better understand the effects an exhaust system has on rwhp and torque.
Big myth busted: your engine needs some back pressure, so stay with 2.5" exhaust over 3.0".
I watched it last night, interesting.

Makes me glad I went with 3".........
Two questions come to immediately to mind. They used no H or X pipe. So what about this harmonic exhaust pulse I keep hearing about? Second they made no mention of the size of the exhaust vs.the power the engine is producing. I'm not convinced a 3" exhaust system would benefit a stock Marauder.
I have heard dual 2.5 should be good to around 600 hp

Interesting, but the video could have been edited to about 1 minute. Editing of course would have left out the Amsoil and Magnaflow commercials. Good information and about as expected. Including an X-pipe or H-pipe would have been interesting.

That engine is twice the size of ours, so it's moving a bunch more air!
I would have liked to see the exhaust less than 20 feet in length lol

2.5" exhaust is fine for the majority of applications , but it has it's limitations as with anything else, my car had the 2.5" stainless works exhaust system when it was on the dyno , it now has a full 3" Vband Stainless Steel Exhaust, and runs much better , next dyno will tell how well.
