I was going to go with the SLP catted xpipe. It all sounds good in the end.

my slp x hangs low as sh*t and the cats scrape a lot. but if youre going o/r then that shouldnt be a problem

Lol I've heard a cobra with bassani catback with a o/r x and it was awsome loud

Hey guys I have the stock H pipe and piping ran out the back on my 07 GT and I was wondering what if anything will be gotten out of changing it? Also I am looking to take the cats off here in the future and put in a O2 tap to avoid the check engine light. But my question is will I have to get the valves re-done to compensate for the loss in back pressure?

Thanks,
David

No, simply removing the cats will not affect the valves.

or just answer the dudes question?

go with the upr its prob less expensive. I got mine off of lethalperformance for i think 150 or so. I fits like a glove the only thing you need to do is change out your driverside manifold studs. When i did mine it the factory studs had a stopper mid way through the bolt which led to an exhaust leak, so then i bought new studs and the upr x pipe fits awesome with no leaks

If you haven't already bought one...keep in mind that the SLP X pipe can be used with both stock headers and longtubes. SLP makes theirs so that a section of pipe can be unbolted and removed for use with their longtubes. I've had their X on my 02 GT for over 3 years now and have never had any problems. I used it with stock headers and now have the SLP longtubes matched up to it. Only thing I will say is that SLP's stuff seems to hang lower than most other brands.
