Hey guys,

I purchased a 2013 C63 (P31) back in April from a forum member and I’ve been having an absolute blast with it. I ordered a Wavetrac LSD and MBH long tubes and will have the car custom tuned on the dyno once the headers are installed. I had some baseline pulls done while going over the exhaust with the folks at Stage Fabrication in NC; we are going with 3” straight pipes into the stock resonator/muffler system.

I didn’t see a dyno sticky, so see attached for the numbers I pulled. Car is 100% stock.

In the meantime, I’ve been doing some routine maintenance such as new fuel injectors, pulleys, brake fluid change, transmission fluid change etc. really enjoying this car and being a part of the AMG community.

Let me know what you guys think of the dyno results and what to look out for/ask when getting it tuned on the dyno.

Graph looks exactly like my stock p31. I also made 402whp stock.

Good to hear. We did 3 pulls and they were all really consistent with the 402rwhp mark. AFR looks pretty solid but will likely change after removing cats and installing long tubes. Standing behind the car in stock form during the pulls was loud - I can't even imagine what it'll be like with these MBH headers! This shop has done a lot of work on BMWs and recently tuned an E55 AMG, so I'm really looking forward to the results.

I recently put on ARH headers and I am sure the sound is probably the same... the noise will honestly make you so happy. But with that said it is LOUD
