CTS Turbo BMW S63 F10 M5/M5C & F06/F12/F13 M6/M6C Downpipes

CTS Turbo BMW F10 M5/M5C & F06/F12/F13 M6/M6C Downpipes are made to maximize exhaust flow for highest power gains. Designed using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from CAST T304 stainless steel; hand TIG welded and back-purged to ensure years of reliable performance. In addition to unleashing the power and performance of your 4.4 Twin Turbo, our downpipes will make your vehicle sound like it really should. When installed with factory exhaust it produces a louder and deeper growl with much more pronounced exhaust "crackle" on downshift. While up-shifting you will enjoy a confident "punch!" as you bang through all 8 gears. The sound will be even louder if you already have an aftermarket exhaust system. Product Details:

• Designed and tested on a real car in the real world
• Cast T304 stainless steel, TIG welded back-purged construction
• Replaces restrictive factory catalytic converter
• Great power upgrade with uncompromising performance
• Incredible sporty exhaust sound, subtle when cruising
• No drone with factory exhaust
