Hi Guys!

Just order a 2012 C63 sedan 2 weeks ago.

Looking forward to drive this beautiful piece of engineering!!!

For the first mod, what U guys suggest? Catback Exhaust or mid-pipe/header ?

Thanks!

I'd start with changing out the yellow side markers to clear, tinting windows and getting a clear bra. Consider light weight, one piece forged wheels and fatter tires. Then when break in is complete, consider tuning mods, especially ECU tune if you don't have the PP.

ok, I order Performance package. But I want to break the car with exhaust. It gonna be more fun!! since stock sound is not very loud for me. So what s your recommandation beside the ecu?

i would just remove the secondary cat and the resonators and you will get a nice roar out of it

That's what i'm planning on doing but kinda worried about the warranty issue haha

just fyi

it would be alot safer to get the ecu tune and the exhaust at the same time. you dont want to take the chance of your engine running lean on account of a freer flowing exhaust. you can get an ecu tune now days for 1000 bucks.

if you get headers, cat back etc. with no tune, you run the risk of scorching the pistons......frowned upon in my experience.

Hi cellryuu!

really? just for a header or a exhaust? since I have order the performance package with some sls internal, I doubt that i need a Ecu retune!

for exemple, on my Subaru STI, at first, I put only the catback and the downpipe and never have an issue with it. Samething with my lotus Elise, only a catback d ont really need a ecu update. Just my 2 cent.

You are wrong, you need to tune with headers on these cars. It just flows so much more that you will run into problems.

If you have P31, enjoy the car till your warranty is up then do headers and mids... Be prepared though, because they are obnoxiously LOUD without cats.
