List of LTH (Long Tube Headers) Manufacturers for C63?
1. KW K3 Coilerovers
2. ECU/Headers/pipes - if Cargraphic checks out I might go with them. If not then I will go with K3 from Kleemann which covers ECU upgrade, a set headers with sport cats, and large trottle system. They throw filters in as well, but I don't think there will be much gain with filters. Should put me around 570 at crank.
3. Evo pulley
4. Just ordered some Rays VR G2s which should cut some serious weight off running OEM rims. Need to decide on some rubber, but shooting for 275 min on rear
5. CF hood arrives on Monday
6. CF front lip diffuser is already and ready for install.
7. CF roof spolier arrived Tuesday
8. RevoSport CF grill on order
9. EvoSport 2-Piece Rotors -back ordered
That would be it. I have already done most of the interior except for CF gauge cluster which I will be ordering from MaCarbon. That should be it for the time been. These things are money-pit!

1) The collector position before the final bend. They really aren't long tubes.
2) The collector size and mid-pipe size (diameter of only 2.75")
These facts are what ultimately swayed me to the MHP headers with their long/smooth collectors (after the final bend) and their 3.00" mid-pipes. I ordered my headers, mid-pipes and swappable cats on Friday!

Cargraphic lists the piping diameter throughout their whole exhaust as 70mm (2.75"). This data came directly from their site. Where did you get 3.00" from?
I would like to know what the primary tube sizes are. It's hard to tell if they are 1 3/4" or 1 7/8" by looking at the photo.
A good comparison shot of the MHP long tubes from avengerboater . . .

In fact because We manufacture them ourselves. We can do a few custom things upon special request. (more on that later
)
