I was going to say take the old ones off first, then install the new ones.

Really funny man did you think of that all by yourself

patience,a friend with a lift,and miller genuine draft.take your time and you'll get it done.also make sure you have all the little bs things like o2 extensions,anti sieze for the header bolts and spark plugs(if you ever want them be able to be removed again) and it is a great time to replaced spark plugs because you have to remove them anyway.the header on the driver side will be a bitch to get in,but what worked for me was to remove the trans mount bolt(auto trans if you have a manual this tip is worthless)and lift the tailshaft as far up as i will go,driver side header slid right in when i did this and i was a hell of a lot easier that removing the motor mount like the instructions said.you might need a bumpstop for the y-pipe i did for my pacesetter lts and ory.i'll be happy help with any questions

to get my driver side header in all i had to do was unbolt the oil sender/blockoff plate thingy right above the oil filter. really wasn't hard at all. they both slid in in a total of about 2 minutes.

biggest helps are having lots of 10mm sockets of different lengths, extensions, swivel joints, different size ratchets, different sized wrenches etc. those things are a pain. and unbolting the coil packs is very helpful too. hardest part is getting of the old manifolds/y pipe. i didn't have to cut my y off but it probably would've been a LOTTT easier.

I left mine on and ended up brusing my arm. i know it sounds weird but its for more space. you dont HAVE to do it. but it does make it easier.

**02transamce** · 05-02-2009, 09:57 PM

ok,i see.didn't really get in my way,that's why i didn't understand

**0verkill** · 05-03-2009, 06:59 AM

the best way to put on slp stuff is to sell it and get some other stuff that is good. but the sticky is a good right up and should get you tru it just fine. its not that bad the hardest parts are geting to the back bolt on the pass side and geting the car high to get the driver side in.

**creeper** · 05-05-2009, 06:17 PM

i originally did mine with the coil packs still on, you can do it, but the pointy spikes on them get pretty annoying when you're doing the back bolt/plug wire
