The Best Systems Start with the Best Materials
Maximize performance in your race built 2015.5-2016 GM 6.6L Duramax LML with the P1 C6045PLM 4" PLM Series Downpipe-Back Competition Exhaust System. Built from heavy duty aluminized steel, the P1 Performance Series 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.
Built to Perform
With the P1 Competition Series you will never have to worry about your exhaust system being the weak link in winning that checkered flag. Mandrel bent tubing, the lowest bend degree angles and extensive dyno tuning guarantee you maximum exhaust flow, maximum horsepower, maximum torque and minimum exhaust gas temperatures.
Easy Installation
P1 systems are as much fun to install as to drive with on your truck. Bolt-on, no weld design makes installing this on your truck a no-hassle project. Everything is direct fit to the OEM hangers and you get all the clamps and parts you will need, all in one box, no matter what configuration of truck you have.
