I'm confused...these are shipped to anywhere in the US but they don't work on LHD cars? did you mean RHD?

Matt47FL

Sorry I F'd up

THESE WILL NOT WORK ON RHD cars

chrisridebike8

no worries. good luck with the sale! seems like a pretty good price. now if I could just convince my wife to get these for me for Christmas...

Mid pipes X or straight?

I just put a used set of these exact headers on our car, and my wife is more thrilled than me!! I know 2K for a set of headers sounds like a lot, but you won't believe how cool your car becomes with them. I've gained a "ton" of respect for my C63 because of them, and such a simple item really don't cost squat, when you consider that you're dealing with a 50 thousand+ car imo.

I'm more worried about having the old headbolts and voiding my extended warranty than price...

what are the gains with these headers?

Matt47FL

The mid pipes are straight, I never opted for an X-pipe or modified the MHP system in any way.

I picked up 45rwhp and 43 rwtq when I added these headers. I had an OE tune and ROW air boxes in addition to the headers.

solekeeper

thanks for the reply, if i don't have a tune and i add these headers what do you think gains would be?

skaarlaj

I wouldn't do it without specific tuning for the headers for safety in the a/f ratio that will most likely lean out.

skaarlaj

Well, I have a 2012 with about 5500 miles with a lot of warranty left, and I simply threw caution to the wind.

I also reused the factory hardware, and gaskets, to secure them to the heads with no problems.

Why wont these work on a coupe?

Matt47FL

I have no idea. I read somewhere that they would not but I have no proof.

Is there even any way to pass smog in CA with these?

abcut973

Catless headers will never pass smog/emission tests.

Matt47FL

You could add cats to the exhaust system, it will hurt the power some but it will make it pass emissions testing.

Isn't CA on the new smog system where they don't use a probe anymore? I know Toronto is on the new emissions system and it's possible to pass. It just checks for the parts to be switching and reading proper signals.

CarHopper

With a tune in NY they can pass. The problem is sometimes tunes dont allow the cars monitors to set to ready mode which makes you fail the inspection. As long as the tune is right and you don't have a sniffer test you'll get through emissions. It doesn't hurt to know someone either who will look away when checking that the cat is physically there.

Just edited the first post. I sold my car today and removed the OE Tune from the car. I have the hand held tuner that I will include with the headers for the $2000 price.

Matt47FL

Make reasonable offer....

abcut973

Are your O2 sensor extensions done properly? No cut wiring harness?
That handheld tuner only works with OE tune right?

Matt47FL

Headers are sold.
