CTS Turbo BMW S58 F97/G01 X3M/X3MC & F98/G02 X4M/X4MC Downpipes

CTS Turbo BMW F97/G01 X3M/X3M Competition and F98/G02 X4M/X4M Competition 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 3.0 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
• 304 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
