X pipes have come from racing. The design improves power and Torque (slightly) by increasing efficiency. The cross-over allows the existing escaping exhaust gases to work in tandem in order to scavenge the next cylinder as the exhaust valve opens. Leaving the cylinder more empty, ready for the next compression stroke.

Straight pipes are best ONLY on huge HP motors. They are unrestrictive and allow for a cleaner flow of gases. The X allows the motor to work more efficiently at all RPM on a motor with more realistic levels of HP.

Thanks that sounds like a beast and your x is very cool! But do you know how it would sound with stock exhaust and resonator delete?

Hi, congrats on your mod, the clips and pics were very very helpful in making my decision to get this mod. I cant wait, i currently have a 2006 3.0. So is the magnaflow xpipe all i need to purchase to get this mod. I also want to do the resonator delete. I tried going to the magnaflow site to purchase the xpipe but it said out of stock, do you guys know of anywhere else where i cant purchase it? Any problems with the xpipe after the install ?
