Are you guys just welding in the Xpipes? I would like to have mine bolted to the Ypipe and welded to the cat back so I can remove each side of the Y pipe seperatly whenever I want. Where would I get the flanges to do something like this? I am running my stock Ypipe into a 2.5 inch into dual 2.25s and I think the 2.5 inch is choking the motor so that is why I want to do the Xpipe. What part number Xpipe would help too. Thanks guys.

 

Lots of muffler shops have standard 2.5" flanges. If not, Jegs or Summit have them. I think I ordered some rom Summit last year.

 

i used a walker x-pipe that the muffler shop ordered for me.i can tell you that it really helped my low end torque.

 

Can you still take the Ypipe down or is it all welded together now? Can you send a pic? Was the Xpipe more than 50 dollars? My truck seems slower since I installed the headers so I think I need an X pipe. cashdudehomie@webtv.net

 

The X replaces the Y. You could get some flanges mounted on each side of the x you can remove it. It would cost about $150. $80 x pipe+$20 flanges+$50 labor. Check out this post for pictures/info. https://ls1tech.com/threads/showflat...31&fpart=1
