Manufactured by STi in Japan, this muffler pair has been designed and engineered to fit directly onto the 2015 WRX STi. Around 1.9kg lighter, the air flow through the mufflers has been increased by 16%, which improves engine response and performance. STi tuning ensures that the tone and sound of the exhaust system is distinct without being intrusive, further enhancing the distinctive burble associated with the marque.
The 95mm twin slash cut tailpipes tuck discreetly into the characteristic bumper of the STi, and are each emblazoned with the STi logo.
The system comes supplied with genuine gaskets and fixings required for installation.
Please note this is a non-stocked item, and is shipped from Japan when you place your order. This will mean a delay of approx 4 – 6 weeks before delivery is made.
