Sport Headers M&M Edition 987.2 with catalytic bypass

"M Edition" Sport Headers with Cat Bypass for 987.2 Caymans and Boxsters with FVD or M sport mufflers. Our M Edition headers and cat bypass pipes were created for those who have already purchased the FVD / M sport mufflers (either TUV or Sound Version). They are a logical progression for those looking for added mid range torque and top end horsepower. Combined with the FVD / M muffler they are by far the lightest, least restrictive, most aggressive sounding system on the market.
