JCR Non Silenced Race Pipe with megaphone tips. I tried both silenced and non silenced on my GT4 and preferred the non silenced GT car sound. Includes the bracket for manual transmission 718's.

From the manufacturer:  "The JCR Titanium Valved Race Pipe is a full direct replacement product for the OEM 718 GT4 and Spyder rear silencer assembly. This version of our 718 GT4 / Spyder / GTS 4.0 Valved Race Pipe includes small diameter straight pipes in the valves closed exhaust route which results in a smaller delta in volume between valves open and closed plus a louder more aggressive sound."
