The MBRP UA2005 solves the reverse fitment challenge from the UA2003: instead of expanding a smaller pipe outward, this adapter\'s 3.5\" outer-diameter end slides directly into a 5\" inner-diameter component, letting builders bolt on MBRP\'s 4\" and 5\" hardware — or any compatible 5\" fitting — without hunting down a custom part.

Built from 100% aluminized steel, this adapter offers a tough, budget-friendly option well suited to dry climates without heavy rain or road salt. Straightforward to install with minimal tools and backed by MBRP\'s 3-year warranty, this is a practical piece for completing a mismatched exhaust connection cleanly on any custom build or system upgrade.
