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.

While I was working on the engine...I had my resonator off along with the whole back of the exhaust....I did not get a chance to drive it like that even thou I kind of regret I didn't but I can tell you its pretty loud...I was having trouble just hearing the engine idling....& when I revved it up it was really a beast...sounded like a race car lol....

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?

OK guys you meke me do it!LOL Since I am in midle east now i am having my uncle make custom one for my 3,0i. I need favour from who ever of you goes under his X5 first. I need measurement how long is resonator? How long X pipe i need to made? I wanna to avoid unneeded welding than is realy required and it will look better too. So how long should X-Pipe be?
Thanks
