All new at Lethal Performance is our own offroad x-pipe made specifically for your 07-09 GT500. Removing the cats has shown to increase power up to 30hp depending on your setup. Most important is that the stock cats won't hold up for long to the abuse of 700+rwhp. We've seen numerous times where a customers stock cats have failed and caused the car not to run properly. That's no more the case as our aluminized steel 2.5" offroad x-pipe simply removes the cats and lets your exhaust flow free. Our pipe is a direct bolt on and requires no welding or cutting. Just remove your stock midpipe from the exhaust manifolds and over axle pipes. Then install our pipe with the supplied hardware and you're done. Our pipe comes with the o2 sensor bungs welded in the stock location so there's no extensions needed.

NOTE: If you have a tune on the car already for an intake or pulley you most likely don't need another tune for the offroad pipe as most tuners turn off the rear 02's and the COT's feature on all of their tunes. If you have a performance tune and are unsure if those 2 features are turned off in the tune just give your tuner a call and ask them. If they say that both features are off then you can run the pipe with no other changes needed to the tune. If the features are not already turned off then you'll need them to do so in order to fully benefit from going cattless and keep from throwing check engine codes. That feature is what the stock tune does to protect the cats from overheating. It basically richens up the A/F by throwing fuel in which cools the cats. Since you're not going to be running cats anymore you want that feature turned off. If not you won't get the full benefit of the offroad pipe as the tune won't hold a steady A/F throughout the RPM range as the car still thinks it has cats and will dump fuel.

If you have any questions about the Lethal Performance GT500 offroad X-pipe please feel free to give us a call.
