Product Overview
Give your truck a bold, finished look with the Sinister Diesel Dual Wall Exhaust Tip. Designed to fit Ford Powerstroke, Dodge Cummins, GM Duramax, and any truck running a true 4" tailpipe, this tip delivers a clean upgrade with aggressive styling.
This exhaust tip is constructed from stainless steel and finished in a durable textured black powder coat, helping resist corrosion while keeping your exhaust looking clean by minimizing visible soot. The dual wall design provides a thicker, more refined appearance, while the angle cut outlet adds a sharp, performance-inspired look.
A brushed stainless Sinister Diesel badge is riveted to the side, adding a premium finishing touch that stands out without being overdone.
Fitment is critical with exhaust tips. This tip is designed to slide over a true 4.00" tailpipe. Many factory and aftermarket systems can vary slightly in size, so it is important to measure your tailpipe before ordering. This tip will NOT properly fit undersized or oversized pipes.
Installation is quick and straightforward with a clamp-on design—no welding required.
