MBRP GMAL401 4-Inch Front Pipe With Flange – For Diesel Trucks, Aluminum

If you’re working on a diesel truck and need a quality front pipe, check out this MBRP GMAL401.

It’s a 4-inch front pipe with a flange, made of aluminum.

It’s a bolt-on part, so installation is pretty straightforward.

Made in Canada, and backed by a 1-year manufacturer warranty.

Just a heads-up—this can’t be sold in California (Prop 65 warning applies).

It’s designed for diesel trucks, so if that’s your ride, this is a solid piece of exhaust gear.

Tubing diameter is 4 inches, and it’s from MBRP, so you know the fit and finish are good.
