Invidia 2022+ Honda Civic Si (1.5T) 70mm N1 Cat Back Exhaust - Burnt TI Tips

This Invidia N1 Cat Back exhaust system is made for the 2022 and newer Honda Civic Si with the 1.5T engine. It replaces the factory exhaust from the catalytic converter back, giving your Si a more aggressive sound and improved exhaust flow. The system features 70mm diameter piping, which is larger than stock, helping the engine breathe more freely.

The N1 series from Invidia is known for its sporty, deep tone that really lets the engine's character come through, especially under acceleration. This particular system is constructed from durable stainless steel for long-lasting performance and corrosion resistance. A notable feature is the pair of burnt titanium exhaust tips, which add a unique, high-performance look to the rear of your Civic Si. The piping diameter of 70mm is chosen to balance increased flow with maintaining good low-end torque, making it a solid choice for daily driving and spirited runs alike.

When installing this cat-back system, you'll typically find it's a direct bolt-on replacement for the factory exhaust, meaning no welding or cutting is usually required. This makes for a more straightforward installation process. You'll notice a more pronounced exhaust note that is deeper and more resonant than the stock system, and potentially a slight improvement in throttle response due to the less restrictive flow. The burnt titanium tips provide a distinctive visual upgrade, setting your Civic Si apart.
