LOL! Nice vid. My girlfriends cousin has a straight pipe from the turbo back and nice big stainless tip (on a 6.0L)... Sounds frickin' awesome! Sounds like a jet while idling...

I have 2.25" mandrel bent stainless steel true-duals with an h-pipe and 3.5"x18" Silverline tips. I love the loud muscle car sound!

 

I've always wanted to ask this...

What's the benefit of an X-Pipe? Added back pressure?

I alway hear guys (especially Mustang guys) talking about, "Yeah, I put that Bassani X-Pipe on there, she really will run now..."

What does an X-Pipe do? Looking it it, and thinkign about airflow, I'm guessing it increases back pressure, and probably yields a gain in low-end performance...

I'd have to think this same low-end benefit robs you on the high end though...

Can someone set the record straight for me, and for those who may not know the gain/loss of an X-Pipe.

 

The idea behind the H and X style crossover is to unite the two banks of cylinders for better exhaust gas scavenging. Instead of two separate banks of four cylinders doing their own work, the crossover uses the pulse created by a firing cylinder of one bank to create a vacuum in the other bank because of surface tension. When a cylinder of the other bank is ready to fire, instead of the piston having to force the exhaust gas out of the cylinder, the vacuum that was created by the other cylinder bank helps suck the exhaust gas out of the cylinder, hence the term "scavenging." X-pipes are known for their increased performance in the med-high RPM range whereas H-pipes are known for their low-med RMP range increase. The reason being is that an X-pipe is smoother/better flowing. X-pipes are also known to tone down an exhaust, while H-pipes are throatier and sometimes known to "pop" depending on the engine. The great the amount of air coming in, the great the performance increase of an X or H-pipe.

 

Haha... One of these days I'll make a video of me driving and some smoke...
