So where an what xpipe are you guys buying when running your true dual setups for the best performance. Are you guys running the 2.25 or 2.5? Right now i just have a cheap flopro si/so dumped.I really want more performance than sound!

 

Run an X pipe whatever size your system as is. Do not run a 2.25" X pipe on a 2.5" system for example.

 

haha definatly would not run a 2.25 on a 2.5 system, I guess its the 4.6 guys that have been using the 2.25 , Darren where did you order your xpipe from and what brand?

 

Well when people get their true duals run a lot of people size down to 2.25" to retain back pressure, mine were done that way when I had them.

 

Mine are stock size 2.5" and they are fine but if I was to do it again I would do them as ChrisAU suggested.

My X-pipe was made by the exhaust shop. Magaflow makes a nice one if you prefer something premade.

You want to install the X-pipe as close to the engine as possible.

 

When you say as close to the engine as possible do you mean even before the cats or do you mean where the pipes Y at?

 

you want to install it were the factory Y-pipe used to be

 

Yes, but not to retain back pressure. 2.25" with an X = max velocity and max exhaust scavenging for the best low RPM torque curve.

 

Man this exhaust stuff gets confusing to me maybe im a little slow

So what exhaust do you guys suggest for the best Performance. Cai and gryphon already ordered and on the way

 

2.25 you gain low end, 2.5 you lose low end. you have a truck witch one makes more since?

 

Im going to order a Magnaflow x pipe from Performance Peddle. Its only $65 with the code "clubgp"

 

You can get the magnaflow knockoff for 30 on ebay, just go on e-bay and type in "x-pipe"

 

^ agreed. Identical replica too.

 

My exhaust guy fabricated it into my intermediate pipes, it works, but not to well. If I ever put in a real X pipe I will take that opportunity to get the $50 stainless one off ebay in 2.25" and convert to 2.25" duals.

 

ok awesome stuff I think im gonna get the xpipe off ebay,and I will be going the 2.25 route,so thanks for the help everyone!
