Product Description

The MBRP UA2003 solves a common exhaust fabrication challenge: connecting a 3.5" exhaust pipe to a larger 5" diameter component without hunting down a hard-to-find custom fitting. This aluminized steel adapter bridges that size gap directly, letting builders bolt on MBRP's 4" and 5" hardware - or any other 5" component - cleanly and reliably.

Built from durable aluminized steel for solid corrosion resistance, this adapter is a practical piece for anyone upgrading an existing exhaust to a larger diameter system or completing a custom fabrication project. Straightforward to install with minimal tools, it keeps mismatched exhaust connections simple and functional without expensive custom work.
