I had flowmaster 40's the later added pypes xpipe. I later decided to take off the flowmasters and replace them with borla stingers. The flows just sounded terrible with the off road xpipe IMO. The borla sounds much better and less raspier.

 

I dont know if i updated this but i ended up goin and cutting my cats out. SOUNDS ALOT better

my advice FTW everybody!

 

I just love the sound of the H- pipe over the x-pipe. I read that someone mentioned 8-10 HP gains but is that to the RWHP or at the crank? Sure I understand it flows better but I doubt a 10HP increase esp if the cats are still in place...JMO

 

Avoid the pypes offroad X-pipe they have sent me 3 wrong x-pipes.

^^^ what did they do, send you one for a new edge?

 

Ordered 2 polished and received both wrong. The whole X was non-polished and just one down pipe the one you bolt in came polished. Then they sent me another one and then it was bent wrong from the factory and it keeps banging against the body.

has anyone else had a problem with the pypes offroad xpipe

 

I had big problems with mine too. They welded the hangar that goes on the passenger side way to farforward and so in the process of install i stripped out a manifold stud tryin to get it tight, needless to say i took ot off and. just reinstalled it yesterday, I took a sawzall to the hangar and now it fits but for some reason even with the mil eliminators from rpm outlet the check engine light is still coming on with a code that says it is lean. not sure why anyone have any ideas?

 

well i got my o/r x from pypes no problems and i bought it from rpmoutlet.com wow i could of had two booboo's at once but no it was good got it in about three days put it on in about an hour and love the sound also no mil eliminators on or a new tune and no check engine light yet knock on wood did i say i love the sound
