Built from heavy duty aluminized steel our Installer Series performance exhaust systems offer a value price without compromising on the quality built into every component. While the seams are a major point of rust through with some budget systems our fully sealed tubing adds years to your system. Constructed to the same specifications as our top of the line Pro Series we back this line with an industry leading 3 Year Warranty. 


MBRPinc's XP Series is the performance exhaust of choice for the enthusiast who needs a system that can take anything that the road throws at it. This system's rugged sixteen gauge T409 construction can be counted on to withstand everything from salt to rocks, tar to grime. We have had such success with this line that we back it with a Lifetime Warranty.

MBRP's Performance Series features aluminized exhaust with NO MUFFLER!  So for those true purists who want unrivaled performance AND sound, this is the kit for you.
