Stainless Works FC13CB-WT 3" Catback Exhaust Vintage Round Muffler Wide Oval Tip

The Stainless Works FC13CB-WT is a 3-inch cat-back exhaust system crafted from premium 304 stainless steel, delivering an aggressive exhaust note and improved exhaust flow. Featuring a classic vintage round muffler paired with a laser-cut, mirror-polished 304 SS wide oval single tip (measuring 11-15/16" x 5"), this system combines performance with a clean, polished aesthetic.

Designed as a factory connect system, this cat-back bolts directly to the OEM exhaust connection point for a straightforward installation. All necessary hardware is included—hangers, clamps, and adapters—for a complete, install-ready experience. For those looking to build a full 3" system, a second flanged adapter is also included, allowing direct connection to Stainless Works Downpipes (FC13DP or FC13DPCAT).
