Product Description

The ST4011 Stainless Cat-Delete Link Pipe allows you to remove the bulky, restrictive OEM catalytic converter (muffler box) and replace it with a lighter, better-flowing stainless steel alternative — all while maintaining compatibility with your current exhaust setup.

Key Features:

•  Direct Fit for All Years/Models

•  Simple 15–20 Minute Installation – No special tools needed

•  Retains Compatibility with OEM Muffler

•  Also Fits Any Slip-On Designed for OEM Cat Setup

•  Noticeable Sound Improvement — Even with stock exhaust

•  No ECU Tune Required
      ⤷ Pipe diameter is optimized to maintain proper back pressure with stock tune

•  Stainless Steel Construction – Durable, heat-resistant, and lightweight

•  Fully Reversible – Can reinstall the OEM cat at any time

Tuning Notes:

While no ECU remap is required to run this cat-delete pipe, performance gains can still be achieved with a tune — even on a fully stock setup. The system is designed to run safely and efficiently with the factory ECU, thanks to proper pipe sizing and flow characteristics.
