Why should you install a performance Catback exhaust on your 2018 Subaru WRX? There’s 4 reasons and 2 other mods you will want.

Installing a Catback exhaust system on the new 2018 Subaru WRX sports sedan will not only improve the appearance, but it will improve performance and give it an enhanced driving experience. There’s two other factory parts available from Subaru you should also consider installing on your WRX, and all three are covered under factory warrantees. The WRX/STI performance parts were developed jointly by Subaru Corporation (Japan); Subaru of America, Inc. (SOA); and Subaru Tecnica International (STI). Here’s why they are worth the price.

STI Catback exhaust

The STI Performance Catback exhaust has four benefits over the stock exhaust system. It will give the stock 2018 WRX a different appearance, an enhanced exhaust note, stainless steel quality, and gives it a bump in power. The stainless steel Catback exhaust has practical benefits that allow exhaust gases to flow more freely, so the 2.0-liter turbo Boxer powerplant “breathes” better, which helps improve overall efficiency. The performance exhaust removes spent gases quickly and easily, and reduces exhaust pressure.

Subaru doesn’t reveal how much power increase there is, but it will effectively improve performance. If you have additional engine mods, it will increase the efficiency and improve the performance of the Catback exhaust system even more. The exhaust system also enhances the sport sedan’s appearance with polished STI exhaust tips stamped with the STI logo. Check out the video on page 2 on how a Catback exhaust works.
