Product Specifications
A Complete Cat-Back Replacement for the 2.2L Cavalier and Sunfire
This cat-back exhaust system is designed for 1995-2005 Chevrolet Cavalier and Pontiac Sunfire models with the factory 2.2L four-cylinder engine. It replaces the entire exhaust run behind the catalytic converter — the intermediate piping, the single muffler, and the tailpipe — so the downstream portion of the exhaust is replaced as one coordinated kit instead of piece by piece.
The system starts at the outlet of the stock catalytic converter and ends at a single-side rear exit with one 4-inch polished tip. The factory catalytic converter stays in place; the kit does not include a converter, a resonator, or an exhaust manifold. Connections are clamp-style, and the listed installation requires no cutting.

Key Features
- Full Cat-Back Coverage: Replaces the whole exhaust path from the catalytic converter outlet to the rear exit — intermediate piping, single muffler, and tailpipe — in one kit, so every component behind the converter is matched to the same 2.2L application instead of being pieced together from separate parts.
- 2.36 in (60 mm) Main Piping: Main tubing is 2.36 inches outside diameter (60 mm). That is the figure to compare if you are measuring an existing system for a like-for-like replacement rather than upsizing or downsizing the pipe.
- 201 Stainless Steel Construction: The tubing and muffler are built from 201 stainless steel with a polished bright-silver finish on the system and tip — a material and finish combination you can weigh directly against other kits when deciding what suits your budget.
- Single N1-Style Muffler, Single-Side Exit: The layout is one muffler with a single 4-inch tip exiting on one side of the rear — the configuration to expect if your car is a single-exit model and you want to keep that outlet arrangement rather than move to a dual or center exit.
- Removable Silencer Insert in the Tip: The 4-inch polished tip includes a removable silencer insert, so the insert can be left in place or taken out — a detail to note before you buy if having a silencer option on the tip matters to you.
- Clamp-Together, No-Cut Installation: The system is a bolt-on design with clamp-style connections and requires no cutting per the specification, and the mounting clamps are included in the box — so no extra hardware needs to be sourced before the install.
What's Included and Not Included
Included in the box:
- Cat-back piping sections (front and rear)
- Single N1-style muffler
- One 4-inch polished tip with removable silencer insert
- Mounting clamps
Not included — reused or separate:
- Catalytic converter — the factory converter is retained, and the system mounts to its outlet
- Resonator — this kit is configured without one
- Exhaust manifold and upstream engine components
Check Before Ordering
- Vehicle application: Confirm your car is a 1995-2005 Chevrolet Cavalier (Base, LS, or RS) or a 1995-2005 Pontiac Sunfire (SE or GT) with the factory 2.2L engine before placing your order.
- Single-exit layout: This is a single-exit, single-side system with one 4-inch tip. If your car's exhaust behind the converter was modified or does not use a single-exit arrangement, verify compatibility first.
- Stock converter assumed: The system mounts to the outlet of the factory catalytic converter, which is not part of this kit. If your converter was replaced with a non-stock unit, confirm the outlet connection matches before ordering.
- Local rules: Aftermarket exhaust requirements vary by state and region. Check street and emissions rules where your vehicle is registered before purchase.
- Not sure? Contact us with your VIN and a description of your current exhaust setup before ordering, and we will confirm the application for you.
