Invidia 2022+ Honda Civic Si (1.5T) 70mm Q300 Cat Back Exhaust - Rolled SS Tips

This Invidia Q300 cat-back exhaust system is what you get when you order part number HS22HS4QD1RSL: the main exhaust piping, the Q300 muffler section, and the rolled stainless steel tips. It's designed specifically for the 2022 and newer Honda Civic Si models equipped with the 1.5T engine. A cat-back system like this replaces the factory exhaust from the catalytic converter back, aiming to improve exhaust flow and deliver a more engaging sound.

The Q300 series from Invidia is known for balancing performance with a more refined sound profile compared to some louder systems. This means you get a sportier tone under acceleration without excessive drone at cruising speeds, making it comfortable for daily driving. The 70mm diameter piping is a step up from stock, allowing the engine to breathe a bit easier, which can lead to a subtle improvement in throttle response. The rolled stainless steel tips add a clean, finished look to the rear of your Civic Si.

When installing a cat-back system, you're typically looking at a bolt-on process that doesn't require welding. It's a popular modification for owners looking to personalize the sound and appearance of their vehicle. This system is a solid option if you want a noticeable change in your Civic Si's exhaust note and a more aggressive look, while still maintaining a comfortable driving experience.
