Fitment, Shipping & Product Support
Free shipping on this MBRP T409 stainless steel muffler.
This MBRP universal muffler is engineered for builders who need reliable tone control, high‑flow performance, and long‑term durability. Constructed from T409 stainless steel, it withstands repeated heat cycles and harsh environments far better than aluminized alternatives. The natural amber coloration is a heat‑tempered finish that develops character over time without affecting structural integrity.
The straight‑through perforated core maintains exhaust velocity while refining tone—ideal for custom systems where flow efficiency and controlled sound are equally important. With a 3-inch inlet/outlet and a 2.5-inch internal core, this muffler is sized for a wide range of fabrication projects, from off‑road rigs to street‑driven performance vehicles.

Verified Fitment
This is a universal‑fit component. It is not designed for a specific Year/Make/Model and requires custom fabrication.
Warranty

Warranty support is provided directly by MBRP and requires proof of purchase. Surface coloration or cosmetic changes from heat, moisture, or road conditions are not considered defects.
Why It Matters
A muffler is a critical tuning component in any performance exhaust system. This unit reduces rasp and drone while preserving flow, helping builders achieve a deeper, more controlled exhaust note without sacrificing power. T409 stainless provides long‑term durability, especially in high‑heat environments where aluminized steel falls short.
