Sportex performance exhaust back box for Ford Fiesta ST150 2.0i built 2004-2009. Single 3" round tailpipe design.

Sportex exhausts are designed to increase engine performance by being less restrictive than standard using free flowing silencers and bends that improve gas flow. Exhaust back pressure is reduced giving noticeable power gains with a deeper sporting exhaust note. Additional power gains are achievable when combined with performance air filters. Each Sportex exhaust is designed to fit to the cars standard system using the original mounting points this applies to both rear silencers and performance systems. For cars fitted with the original Ford exhaust system the existing back box has to be cut from the exhaust system and the Sportex one will then fit to the Ford system. Sportex exhausts are constructed using high quality aluminised steel for the pipe work and silencers and T304 polished stainless steel for the tailpipes. An excellent choice of tailpipe options is available to improve your cars looks from subtle round designs to stylish Boxsta ovals. The Sportex performance exhaust range is backed up with 24 month guarantee and best of all offer great value for money.

Sportex ST150 back box Good price, well made and easy to fit. Bit too loud for me personally, but makes some great popping noises on change down!

Nice sound and great value for money Very impressed with the item,great value for money and has a nice sporty sound,highly recommend

sportex back box i fitted a sportex back exhaust box to my fiesta st 150,not only did it sound great it actually improved the performance i did not expect this. i will say if you are after an after market exhaust to replace a rusted out one, beware the sportex is not quiet hope this helps you decide
