So i just got my downpipe earlier this week and am looking to install it over the weekend. Im going to bolt it up to the stock manifold, which appears to have corroded studs, and on the bottom to my option/tsudo catback. i have the gaskets i need, but i have not done anything like this before, anybody have any tips for a newbie? what tools i need, and how much time will this take me?

your going to need a ton of patience to break those three bolts loose where it connects to the manifold.. thats my best advice other than that its pretty much self explanatory and simple


I did my buddies dp on his 2.2 and it took a bunch of patience, a torch, some sore hands, and an hour of our lives to figure out how to get those bolts loose.. hopefully you have better luck than we did!

how long do i heat it up before i can go to town on those bolts? after heating them will i still have to have superhuman strength to break them free?

Pb blaster the **** out of those bolts and just try and break them loose with a socket.

i read somewhere that a 1:1 mix of acetone and atf is supposed to kick butt as a rust penetrant, anybody try this?

CobaltItaliano

Not sure about that. But I know when I did my buddies full exhaust we just heated the bolts up red hot and used vice grips to bust em loose. Came off simple after half a can of pb blaster didnt work

wd 40 helps too

well im borrowing a blowtorch from work, i got some pb at home, just picked up an o2 sensor socket..... id sayy im just about good to go cause the rest is just basic tools right?

Pb blaster and impact wrench

Does your blowtorch have oxyacetelyne (spelling?) and oxygen or is it just a propane torch, because if its just a propane torch its probably not going to get hot enough. I've done alot of exhausts and without an actual torch the bolts just snap or the nuts strip.

I've found penetrating fluids to just be a waste of money on exhaust parts because without heat nothing comes apart unless its a year old or newer

Not really. Thats a lubricant not a penetrating oil

mikeman428

Actually got it off without using the torch, that ATF Acetone mix worked like a charm! the new pipe is on now and it sounds amazing

haha good luck breaking loose the O2 sensors that was the best part

Just use something for leverage and it can't be that bad

If you soak it up a few hours before getting to it WD40 works really good.
I did my exhaust with wd 40 and a socket, and my car was 3 years old and never touched exhaust before.

I unplugged mine from the harness and pulled the pipes out before touching them.. put the DP down on the vise and break them loose with a wrench and a piece of steel pipe over it for leverage.

O2 sensors are some nice knuckle busters

I think I snapped off 2 outta 3 downpipe bolts when installed my header and that was after fighting them for a good hour. Those things are a bitch

mikeman428

Surprisingly only issue i ran into was the lower o2 sensor... ended up just replacing it

That one made me fall on my ass when I broke it loose.

Pb blaster or wd40 will do the trick...
