i think you know what it means

 

Last question for ya guys. Whats better for performance and sound wise. X pipes or H pipes? Im seein that the X pipe is a little more expensive, but only a few dollars. I heard that the air flow is much nicer with H pipes though. I do have the SLP 2 Loudmouth exhaust on there. I swear this is the last question about htese damn midpipes lol

 

some people dont like x pipes and LMs, I personally like em, and x pipe flows better and have a more efficeint scavenging effect. When one bank pulsates exhaust through the x, it creates a vacuum on the other bank and pulls the exhaust out, giving it more power, although, it will be little and barely noticable

 

Get which ever you like the sound of.
A MAC Prochamber sounds awesome with Loudmouth 2's
