Catback Exhaust System for Chevy Cavalier Pontiac Sunfire (1996-2001)

High-Flow 2.5-Inch Stainless Catback for 1996-2001 Chevy Cavalier & Pontiac Sunfire GM 122 / LD9 Twin Cam

Who It’s For: Designed specifically for Chevy Cavalier and Pontiac Sunfire owners running the GM 122 (2.2L) or the high-revving LD9 Twin Cam (2.4L) engines. This is for the enthusiast who wants to shed the restrictive factory piping for a deeper, more aggressive exhaust note and improved throttle response.

The Problem: The factory exhaust on the J-Body platform is a notorious bottleneck. Constructed from narrow, mild steel that is prone to corrosion, the stock system stifles the Quad 4 and LD9 Twin Cam engines at higher RPMs. If you’re still running the original pipe, you’re dealing with restricted flow and a tinny, uninspired sound that doesn’t match the car’s tuning potential.

The Solution: We engineered this system with 2.5" mandrel-bent stainless steel to correct the breathing issues inherent in the stock design. By increasing the diameter and smoothing out the flow, we allow the engine to evacuate gases more efficiently. The result is a system that holds up against the elements and provides a mature, deep tone that eliminates the "rasp" often found in smaller-diameter aftermarket setups.

Why This is the Ultimate Upgrade

• Optimized Flow: The 2.5" T304 stainless steel piping reduces backpressure, allowing the LD9 Twin Cam to breathe better through the mid-range and top-end.
• Enthusiast Grade Finish: Features a fully polished 100% stainless steel build for maximum corrosion resistance and a show-quality look under the rear bumper.
• Tunable Sound: The oversized 4.5" tip includes a removable double-layer silencer, giving you the ability to dampen the sound for daily commutes or open it up for the track.
