CTS Turbo race downpipe set for Mercedes Benz C43 C400 C450 E43 E400 E450 with M276 engine

CTS Turbo race downpipe set for Mercedes Benz C43 AMG, C400, C450 AMG, E43 AMG, E400 and E450 AMG with M276 engine is 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 part. 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 the gears. The sound will be even louder if you already have an aftermarket exhaust system. Product Details:

• 3" downpipes with heatshielding
• Cast T304 stainless steel, TIG welded back-purged construction
• Fits within OEM heat shields
• Great power upgrade with uncompromising performance
• Incredible sporty exhaust sound, subtle when cruising
• No drone with factory exhaust
• Replaces OE numbers: 276-140-94-13  and 276-140-96-13 (check your vehicle to make sure you have the "short" factory part)
