Suggestions for Header Removal and replacment
 

So, i have started tearing into my header, downpipes, exhaust... got exhaust and downpipes(cats) off... the header, what a pain... first getting the heatsheild off the driver side, just pretty much had to get angry and i finnaly got it outa there... but the nuts are a pain in my ***. anyways any tips for getting these is helpful, also when putting new stuff in can i attach the downpipes to header before we put them in? will it clear?

You need different lengths wrenches. I picked up a set of shorty wrenches that helped out a little. Just keep working at it and it will come off. The easiest way is to lower the engine by about 3 inches but not everybody has a lift to do this. But it can be done with the engine in place just make sure you get everything straight before tightning the bolts on the headers during installation. As far as putting on the cats to the headers you can clear putting them on together but it will take two people to hold it into place from the bottom to get the bolts started and hold it until you get them tight to ensure a good seal.

anyone who has taken off the stock header, on the driver side we got all the bolts out and everything but can't wiggle the thing outa location, any suggestions? did you remove anything? ty

I forgot about that. the steering linkage is in the way. you can loosen the bold that holds it in place an lift up and it will disconnect. just ensure you mark both sides and dont let it spin around (etc) that way you can put it back together in the same location. it will be tricky to line it up and you will think it wont go back in but just keep working at it and it will go.

you could take a look at my DIY thread that I did long time ago ... it could help you a little bit ! :)
