mine is starting to turn blue also, had it on since wednesday, 80 miles a day highway driving for me

 

Yours will eventually turn blue too. I had a stainless header on my Prelude and it turned gold after a couple of days, but never turned blue until about two weeks.

 

Read through the dyno's again. For one of them we had a header back exhaust for both sessions. The only delta is the header (i.e. the "test pipe" was on for both runs).

 

Sweet! Can't wait.

 

Here's the general low down on the install. As others has incurred, it should be about 2hrs.

Remove black battery heat sheild

Remove header from cylinder head, but leave one nut hand tight on there so it doesn't drop on you

Go under the car

Unclip the O2 sensor

Remove the stock header bracket

Remove 2 spring bolts at header/cat option

Now loosen that last nut on the header.

Drop the header from the bottom of the car

Now the install is reverse from removal.

Other tips:

header is re-installed from the bottom of the car, and pushed up into the engine bay.

use anti-sieze on the head studs and O2 sensor

when retorqeing the header, start from the inside of the flange, then work your way out, alternating from left to right. (think of what you do with wheel studs).

 

just read through the dyno's again, for the AP1 you did a baseline with K&N and snorkel, the testing delta was the Berk TP + Header, you managed to gain, 5whp........

 

how much is it?

 

dynooooooooooooo

 

i just had mine installed..... b/c of the shape, it involved taking one of the engine mounts off . .anyone else?

 

I heard thats not too uncommon...I'll report back when I install mine
