That looks good! did you manage to take any pics of the install?? did they need to move/tilt/adjust the engine to get the headers to fit??
How long did it take to install?
Any sound clips to hear how loud it is on idle?
Wow, that looks nice, and really shows how crappy the stock manifolds are. Maybe if the headers had some coating on them, so they weren't so shinny, they may be able to sneak thru our visual emissions inspection... that's the one thing holding me back at this point. I'd like to hear from some californian's who have gotten thru smog tests. (mainly the visual inspection)
Thanks Atomic 80 - you da man! I'm not sure why the upload got aborted but I knew you were the one to call on to fix it.
When I stopped by the shop yesterday afternoon the headers had been installed as in the photos. My tech started it up earlier (with no exhaust) and I'm told the guys went running for their earplugs! It gets welded up today but as I'm having fluid changes and flushes done also I probably won't get it back until Friday. They gave me an E60 530 loaner so I don't mind. BTW I'm surprised how much of a driver's car the latter is, with a very firm suspension and steering that feels as if it's barely assisted. Still, it's hard to warm up to the E60 in many other respects.
The headers are the tubular version, ceramic coated and polished, mated to a SuperSprint exhaust. My tech told me before the install that the engine would have to be lifted a small amount, although he mentioned it would only take a half hour to do that so no big deal. He also said the headers and exhaust would require a little "hand-fitting" to get everything lined up exactly right, but that's why he works on my cars as he's a perfectionist.
I'm assuming based on everything I've read I'll get 30+ crank HP with the headers/exhaust ***'y and the PowerChip 94 octane software. Looking at the pre-dented, pre-restricted factory headers that figure may be conservative. In any case, better throttle response and a freer-revving motor are what I'm after. Obviously I'm not going to be totally able to separate the effect of the headers and the s/w. Off to the shop now to take a look!
