Invidia 01+ Civic EX 2DR/4DR 60mm (101mm tip) Cat-back Exhaust

This Invidia cat-back exhaust system is specifically for the 2001-2005 Honda Civic EX models, whether you have the 2-door or 4-door version. What you get in the box is the complete cat-back assembly, ready to bolt up behind your catalytic converter. It's designed to replace your factory muffler and exhaust piping, giving your Civic a more distinct sound and a sportier appearance, especially with its substantial 101mm exhaust tip.

The system uses 60mm diameter piping, which is a common size for naturally aspirated engines like the one in your Civic EX. This diameter helps to improve exhaust flow compared to the stock system without being so large that it sacrifices low-end torque. The piping is constructed from durable stainless steel, chosen for its resistance to corrosion and its ability to withstand the heat and stresses of daily driving. The large 101mm tip is polished to a mirror finish, providing a noticeable visual upgrade to the rear of your car. This setup is a popular choice for Civic owners looking for a well-built exhaust that balances sound, performance, and aesthetics.

When installing this cat-back system, you'll typically be bolting it directly to your existing catalytic converter and using the factory hanger locations. It's a direct bolt-on installation, meaning no welding or cutting is usually required, making it a manageable project for many DIYers. You'll notice a deeper, more aggressive exhaust note when you accelerate, and the improved exhaust flow can contribute to a slightly more responsive feel from the engine. This Invidia cat-back is a solid option for enhancing your 2001-2005 Civic EX.
