Keep your Peterbilt 330, 335, or 337 in top shape with our line of durable exhaust elbows, piping, and similar exhaust components built for heavy-duty performance. This lineup includes essential parts like Y-pipes, adapters, and elbows crafted from tough aluminized or chrome-plated steel to handle the rigors of the road. Whether you're replacing worn-out pieces or upgrading your truck's style, these components offer reliability and a polished finish. Each aftermarket part is designed for Peterbilt models 330/335/337. Aftermarket exhaust parts can enhance the overall look of your rig and add to its functionality, preventing exhaust gas from entering the gab and optimizing backpressure in the pipes.
