They would be a good addition to this DIY!

Just found 33ft/lbs. for the header bolts... Can anyone verify this? What about the cowl bolts and the steering rack bushing bracket with the wire harness attached to it?

DCRH installed. Took three and a half hours on the ground with a friend. I got all the bolts from the head off through the top. Seemed so much easier. Everything when together perfectly. FYI my car is stock sounds pretty good for just a header. REFLASH IS NEXT !!!

A lot of people recommend starting with a cat back first. Is there any reason you went this direction?

I'm thinking of going this direction as well.

To me the header is a great start. You get a better flow using a header and you also eliminate the cat.(less bends=more power) You just free up power by also not going through the cat. I don't like loud ass cars so I might go with greddy sp2 or something later.

I did my header last, after my intake, exhaust and boltons.

Reflash, is definitely next

Installed my DCRH the other day. Good bang for the buck no doubt. My only gripe is the rattle that I have now after installing it. It's pretty intermittent and seems to be coming from below the shifter, I plan on putting it back up in the air later this week when I install my SPC camber arms... I'll be sure to post up the fix when I find it.

My plan of attack:

1.) Verify that the O2 sensors and/or exhaust piping aren't hitting anything when the engine torques during start up or when hitting road bumps.

2.) Install some polyurethane exhaust hangers to thwart excessive movement.

I hypothesize that because the rubber exhaust hangers are warm and more pliable that they are allowing more exhaust movement. I plan on putting the car back up in the air later this week to have a look when I install my SPC camber arms... I'll be sure to post up the fix when I find it.

What kind of extensions are we talking about for this? I've already done the IMG install which was a pain in the ass. The header bolts seem to be giving everyone trouble. I have no lift and don't REALLY want to spend 5 hours doing it. 2 sounds much better lol. I have a pretty basic set of tools with maybe 3"/6" extensions.

You are going to need some long ass extentions. I used 2 12" extentions end on end for the CV shaft housing. You can get these for dirt cheap at Autozone if you don't mind buying crap brand tools (IMHO it makes no difference as long as it gets the job done

). May I also suggest getting some ratcheting box end wrenches too, I find these to be invaluable on almost every project.

ibanez37 · 10-15-2007, 04:29 PM

Lol I figured I would need something that long.. I think you're going to make me broke on getting a set of nice ratcheting box end wrenches though haha. If you think they might get the job done quicker on something in this install, I might take your advice and go get the specific sizes

What exactly are the extensions used on? Just the top two bolts for the header?

caveman74 · 10-15-2007, 05:52 PM

The bottom ones I used the LONG extention. The top 3 I got from the engine bay
