Corsa Pro Series Weld-In Packed Resonator - 3.5 in, 13.5 in OAL, 4-6 dB - Brushed

A straight-through packed resonator built from 304 stainless steel in a brushed finish, using a perforated stainless core wrapped in packing rather than chambers or baffles, so it suppresses drone without adding restriction. The 3.5 in center in and center out ports and 13.5 in overall length suit larger diameter custom systems, and the body is reversible so it can be installed in either direction. Corsa rates it at 4 to 6 decibels of reduction, enough to work as a standalone muffler for a mild to moderate, drone free exhaust note.
