Description
Catback Exhaust System — Stainless Steel

Bolt-on stainless steel catback that flows better and sounds meaner than stock. Engineered for direct bolt-up at the catalytic converter, this system replaces everything downstream with mandrel-bent tubing and a performance-tuned muffler. Corrosion-resistant throughout—built to handle trail duty and road miles alike.

✓ Ships from FL Warehouse ✓ Stainless Steel Construction ✓ Direct-from-Warehouse
Key Features

Frequently Asked Questions

Do I need any hardware or gaskets to install this?

You'll need a new gasket at the catback connection point—most shops grab one during install. Bolts are typically reusable. Confirm gasket size with your parts supplier before install day.

Will this affect my check engine light or require a tune?

Catback systems bolt on after the O2 sensors, so they don't trigger codes. No tune needed—plug and play from a diagnostic standpoint.

Can I install this myself with basic tools?

Yes. You'll need jack stands, jack, basic hand tools, and a lift or ramps. Plan for 1–2 hours if you're comfortable under a vehicle. A second set of hands makes alignment easier.
