• Gintani C63 AMG M156 V8 Header Back Exhaust Development + Dynos

      Gintani is wrapping up development of their C63 AMG exhaust. After the final round of testing the car was flashed back to stock and here we have a dyno of the car from the baseline stock to with the exhaust and tune. Stock the car put down 360 whp and with the exhaust alone on 91 octane the car put out 402.0 whp. A very, very nice gain with exhaust alone. Expect pricing information to come shortly.

        is this exhaust actually straight pipe all the way? it looks like there is a spot where it could work like an x-pipe, unless it's just welding to keep the both sides together but no opening between the 2

        40rwhp from that exhaust alone is pure BS. I have straight pipes without cats on my C63. I gained about 15hp. Headers gave me about 44hp. The exhaust system above has cats. There is no way in hell your going to get 40hp without headers

        This exhaust sounds amazing. Spent a week in this car. HATE AMG sound normally till I heard this one.

        I was under the impression that Gintani already had headers, which Jeremy ran 11.0 @ 127 mph with at Sacramento.... are these new ones?
