Product Specifications

Cat-Back Exhaust System for the 2002–2006 Acura RSX (DC5)

This Flashark cat-back exhaust is a complete replacement for the factory exhaust sections behind the catalytic converter on the 2002–2006 Acura RSX (DC5) coupe. It is listed for RSX Type-S and Base models with the 2.0L four-cylinder engine, and it pairs 2.36 in OD mandrel-bent stainless main piping with a polished muffler section and a 4 in burnt-finish tip. Clamps, gaskets, bolts, and nuts are included in the kit.

The system is built around the stock catalytic converter. Flashark describes it as a bolt-on design whose flanges connect at the factory converter outlet, with no cutting or welding required. Because the kit starts at the converter, the catalytic converter stays in place, and the system does not include a header, downpipe, test pipe, or converter of its own.

Key Features

  • True cat-back coverage: The kit replaces the exhaust from the catalytic converter outlet to the rear of the RSX, so the factory converter and everything ahead of it stay in place. That is the exact scope to expect before you order.
  • 2.36 in OD mandrel-bent main piping: The main pipes are formed with mandrel bends to hold a consistent diameter through curved sections, and the size is stated as outside diameter. This is the pipe figure to compare when matching the kit to your existing setup.
  • 201 stainless steel with polished surfaces: The system is built from 201 stainless steel with polished silver surfaces, CNC-machined flanges, and TIG-welded joints, which defines the finished look of the system and its connection points.
  • 4 in burnt-finish tip: The muffler outlet uses a 4 in tip with a burnt finish, giving the rear of the car a distinct aftermarket look rather than a plain polished outlet.
  • Bolt-on connection at the factory converter: Flashark specifies a bolt-on installation with flanges that meet the factory catalytic converter outlet, so no cutting or welding is described for a standard install.
  • Mounting hardware included: Clamps, gaskets, and installation hardware ship with the kit, so the mounting parts do not need to be sourced separately.

What's Included and Not Included

  • Included: All exhaust piping and muffler sections from the catalytic converter outlet back to the rear of the vehicle, including the polished muffler section with the 4 in burnt-finish tip.
  • Included: Clamps, gaskets, and installation hardware.
  • Not included: The catalytic converter, header, downpipe, or test pipe. The factory catalytic converter is retained on the vehicle.

Check Before Ordering

  • Confirm your vehicle matches the fitment row above: a 2002–2006 Acura RSX 2-door coupe with the 2.0L four-cylinder engine (Type-S and Base models are listed). Verify the engine and body configuration of your specific car before purchase.
  • The kit is a cat-back system, so it connects at the outlet of the factory catalytic converter. Confirm your RSX still has its stock converter and that the converter outlet area is in serviceable condition.
  • If your vehicle has been modified ahead of the converter or uses a non-stock converter, confirm compatibility with your setup before ordering.
