Invidia 88-91 CRX EF8 60mm (101mm tip) N1 Cat-back Exhaust

If you're looking to give your 1988-1991 Honda CRX a more aggressive exhaust note and improved flow, this Invidia N1 cat-back exhaust system is a solid choice. Designed specifically for the EF8 chassis, it replaces the factory muffler and piping from the catalytic converter back, aiming to reduce backpressure and let that engine breathe a little easier. This can lead to a more satisfying sound under acceleration and potentially a small bump in performance.

Invidia is known for building well-made exhaust components, and this N1 system is no exception. It features 60mm diameter piping, which is a common and effective size for naturally aspirated engines like the one in your CRX, balancing flow with maintaining good low-end torque. The large 101mm polished stainless steel tip gives the rear of the car a more substantial look. The system is constructed from SUS304 stainless steel, which is chosen for its resistance to corrosion and its ability to hold up over time, even with the heat cycles an exhaust system endures. Installation is typically a bolt-on affair, replacing your stock system without requiring welding or cutting, though you'll want to ensure all connections are sealed properly.

This cat-back system is designed to bolt directly to your existing catalytic converter. While it's engineered for a direct fit, it's always a good idea to check your factory exhaust hangers and ensure they are in good condition before installation, as they will be reused. The result is a sportier sound that many enthusiasts appreciate, especially when paired with other intake modifications.
