A cat-back exhaust for the TRX where the middle section is a swappable module. Three modules come in the kit and each changes the sound, from a noise-cancelling section for quiet highway driving through a standard muffler to a straight-pipe section, and they clamp in and out with v-band clamps.
why this one — The TRX has had no exhaust in this catalog at all until now, and this is the one that solves the real problem with a 702 hp truck, which is that the sound you want on an empty road is not the sound you want on a four-hour drive. Swapping modules takes clamps, not a shop visit. Two things to know before you commit: at 3,455 dollars it is the most expensive exhaust in this lane by a long way, and MagnaFlow showed it out of stock when we checked.
- Requires: TRX only - the 6.2L supercharged Hellcat engine. MagnaFlow listed this as out of stock when checked on 2026-07-26.
