Invidia 01-06 Acura RSX DC5 Type-S 60mm (101mm tip) Cat-back Exhaust

If you're looking to give your 2002-2006 Acura RSX Type-S a more aggressive exhaust note and better flow, this Invidia cat-back exhaust system is a solid choice. It replaces the factory exhaust from the catalytic converter back, aiming to reduce backpressure and let that K20 engine breathe a little easier. You'll notice a deeper, sportier tone that really lets you hear the engine when you get on it, without being overly obnoxious for daily driving.

This system is constructed from durable stainless steel, which is known for its resistance to corrosion and its ability to hold up well under the stresses of being part of your car's exhaust. The piping measures 60mm in diameter, which is a common and effective size for naturally aspirated RSX builds, balancing flow improvements with maintaining good low-end torque. The exhaust tip is a substantial 101mm, giving the rear of your RSX a more muscular appearance. Installation is designed to be a direct bolt-on affair, using the factory mounting points, so you won't need to cut or weld anything to get this fitted.

When installing a cat-back system like this, it's always a good idea to check the condition of your existing hangers and any connections further up the exhaust. Sometimes, old rubber hangers can be brittle and may need replacing to ensure the new system hangs correctly and doesn't vibrate against the chassis. This Invidia cat-back is a popular option for RSX owners looking for a noticeable improvement in sound and a cleaner look for their exhaust system.
