Hi guys ~ i'm from e63 and just wondering which car would be faster given

some couple tune.

2009 w204 c63 amg with BMC drop in filters+ resonator delete ,

+19"light weight wheels + rest stock.

2008 w211 e62 amg with BMC drop in filters+ PLM shorty header

+secondary cat delete with 3 inch Xpipe

+resonator delete + muffler delete + rest stock

witch one do you think it'll be faster ???

do both cars have ECU tune?

nysid2007

No ECU tune, Stock.

it seems to me the second one would be faster.

the shorty headers, 3 inch x-pipe and seconday cat delete remove some restriction letting the engine breathe more.

Are those shorty headers cancelling the primary cats?

nysid2007

No , not at the moment. How much would it be quicker ~ I know it'll just be

an assumption but just curious if e63 has any chance ~

Also if primary cats are deleted how much quicker than having it on .

thank you for your thoughts and time !!

mainly deleting the primary cats will give the most power and difference from deleting the seconday cats. But you must tune the ECU if you want primary cat delete or else you might be losing power since you will get the check engine light if the ECU is not tuned.
You will feel the difference in performance when primary cats are deleted.

If only the secondary cats are deleted, while leaving the primary, the gain most likely will be around 5 wheel horsepower.

Resonator delete don't effect power that much.

I'd say the E63 despite the weight diff. When Superlubricity had the PLMs, it did show a small gain.

Bench racing at its finest.

yeah so what you think??? I'm gonna bench race first because

c63 has bent passenger side front wheel with two rear tire gone.

Just waiting for a new wheel and pair of PSS . Till then BENCH RACE~

derspi

Good for you then. This thread will redeem itself once you post the results of the race - even better if you have a video to go with it. But until then, this thread and bench racing, in general, will continue to be lame.

thank you for your guidance. which I wasnt really looking for . ..... I was more

interested to see other peoples thoughts on bench racing not how to

make my thread better.
