This 4" CAT delete pipe for the 07-10 LMM Duramax, bolts directly to the factory or aftermarket up-pipe which bolts to the turbocharger. Installing this CAT delete pipe will eliminate the diesel oxidation catalyst / catalytic converter. You will need to re-use the v-band clamp that is currently being used to fasten the downpipe to the up-pipe. At the other end it's secured using a 4 bolt laser cut flange. This CAT delete pipe will fit all Chevy Silverado & GMC Sierra 2500/3500 bed & cab configurations. Installation takes approx. 1hr, with no cutting required. Choose between aluminized steel and T409 stainless steel. Aluminized steel is our best seller and the most popular. However, we suggest the stainless upgrade for those who regularly operate there truck on salted winter roads. Removal of the CAT involves removing and eliminating emission related sensors. Because of this, when installing a CAT delete pipe it must also be used with a tuner that can delete the DPF. The H&S Mini Maxx is our most popular tuner for the LMM. Expect to increase fuel mileage 3-4 mpg. More or less depending on the current state of your catalytic converter. Typically we see around 18-19 mpg combined mileage, when both the DPF & CAT are deleted. There's a 1 year warranty for aluminized & 6 year warranty for stainless. Don't waste your time with the china knock-offs. Install this quality; Made in the USA CAT delete pipe. We've installed & tested every CAT delete pipe available for the 07-10 6.6 LMM Duramax.
