GMC/Chevy, 2012-2018, 6.0L, Clamp/On - Truck Cat-Back Dual Exhaust KitsMake That Chevy or GMC sound and perform the way it should by increasing the exhaust flow and enhancing overall power. More power means you don't have to mash the go pedal as hard, and as a benefit, you will see a 2 4 mile per gallon increase on the highway. Sound: MPI Turbo series mufflers are going to have a nice mellow sound, with a slightly higher noise level than stock with a lower tone, making it sound like a truck instead of a Hoover vacuum.

Good for the $$$
Worked great on my Mercruiser Alpha One Gen 2. Once the bottom unit of the outdrive is off and cleaned it only takes a few minutes to install impeller, seals and housing. A very affordable alternative to taking it to the shop.

Fit perfectly and very complete set of parts
Had everything I needed plus some extra parts in the kit. I probably could have just replaced the impeller for slightly less but while everything was disassembled you might as well replace the works. Included - Water Pump Impeller, Housing, Key, Face Plate, Face Plate Gasket, O-Ring, Seal Face and Carrier Assembly Oil Seal
