Borla 17-19 Honda Civic SI 1.5L Turbo MT S-Type 2.75in Cat-Back Exhaust

If you're looking to get more sound and performance out of your 2017-2020 Honda Civic Si, this Borla S-Type cat-back exhaust system is a solid choice. It's designed to replace your factory exhaust from the catalytic converter back, giving your 1.5L turbo engine a more aggressive tone and potentially freeing up some horsepower.

Borla builds this system using T-304 austenitic stainless steel, which is a strong material that resists corrosion much better than the T-400 series stainless steel you might find on some other exhausts. The exhaust pipes feature smooth, mandrel-bent curves to ensure exhaust gases flow as freely as possible, which helps with both power and sound. The S-Type designation means it's tuned for a sportier sound that's noticeable but still comfortable for daily driving, and it comes with polished T-304 stainless steel tips that look sharp under the car.

This is a complete cat-back system, meaning it includes everything from the mid-pipe back to the mufflers and tips. It's designed for a direct fit on the 2-door coupe Si model with a manual transmission. Borla backs this system with their Million-Mile Warranty, so you can be confident in its long-term durability.
