VW Polo GTI (6C) 1.8 TSI (15-17) Cat Back Performance Exhaust

Transform the soundtrack and style of your Volkswagen Polo 6C GTI 1.8 TSI

Give your 2015, 2016 or 2017 Polo GTI 1.8 turbo a serious upgrade with this UK engineered stainless rear section system. Built by Cobra Sport from premium T304 stainless steel with mandrel bends and expert TIG welds, this cat-back upgrade delivers a deeper, sportier tone, sharper aesthetics and quality you can feel every time you drive.

We have fitted this system on customer cars and our own demo vehicles. The feedback is consistently positive about the refined sound, precision fitment and immaculate finish. If you want a durable stainless solution that elevates everyday driving and looks the part behind the bumper, this is the one.

Why enthusiasts choose this stainless system

• 63.5 mm pipework from the catalyst rearwards for enhanced gas flow
