Complete super high performance system for all Boxster cars. This is the ONLY unique system available anywhere in the world. Each and every other systems is a MAJOR compromise in power and sound as all stock OEM Porsche and aftermarket Boxster mufflers Boxster use 1.5" rear inlet TUBES for filling the muffler. Therefore they are all limited in flow and power. Fabspeed MAXFLO systems features 2.0" 50.2mm pipes that connect to a dedicated high performance muffler system. Complete Boxster dual outlet muffler with mirror show polished tips.
