i swaped dp on my s/c about 40 mins and im handicap when it comes to car modding

 

is the header to head gasket manditory?

zzp told me the stock gasket would be fine, just wasn't sure

 

Very nice how to man.

 

Its not manditory in all cases.. but while your in there, its nice to put one in to be safe..The last thing you want is an exhaust leak. + They are pretty cheap.
Thanks man! glad its helping people!

 

lol tell me about it. lucky for me i have two leaks right now. they are so annoying and embarrassing..

just ordered one from napa. they said they didnt have anything on file for a 2006 so i got one for a 2005. gonna be like $17

 

nice write up... is the headers really the only thing i need 2 change on my exhuast system... that and maybe a muffler delete

 

my second o2 has now decided that my cat isnt doing a good enough job. it was fine for 2 weeks, then last week it turned the CEL on. i have the high flow cat. i know that you can fool the o2 with a tune, but is there any other way to fool it?? thanks

 

anyone??

 

The best way is obviously with a tune. But there are little resisters called antifoulers that you splice into the O2 sensor wires. I don't know much about them though. I've never had to use one..

Maybe start a new thread about it?

 

Hey,

I'm in the process of installing the zzp header/dp combo on my 2.2L. For the life of me, I can't break the 3 15mm header to manifold nuts loose Did you do it from the top or bottom? I've only been trying from the top (for an hour). I use lots of PB Blaster but the bastards are really stuck.

Thanks

 

I went at it from the bottom. try using a few extentions so you can get some leverage. BTW If you are replacing both the header and DP you shouldn't have to undo the header/DP connection. Just take them out in a solid piece

 

i was looking on alldata and it is showing that the header nuts be torqued to 10 ft lbs which is 120 in lbs.
The graphic here is showing 106 in lbs, that a big difference, which one is right?

 

nice how to! im doing this next

 

lol maybe split the difference?
Thanks, Hope this can help you out!

 

I installed a obx header and dp I got from JTLucas (forum member). After the initial install i had a leak on the passenger side of the header somewhere, so today, I took it off and put the factory gasket back on, as it was still in great cond. I torqued all the bolts down correctly and in order. Also, when I had the header off this time, I checked to see if there was anything on the block. I cranked it up and still a leak in the same spot.
Any ideas? maybe a better type of gasket?

 

Chances are, the flange is warped.. but there are thicker gaskets that can sometimes fix this issue..

Check out http://www.remflex.com/ they have some good gaskets!

 

nice how too, helped alot. Althought removing the downpipe from the exhaust was damn near impossible with a normal wrench. thank god i had an impact gun!

 

I just installed a XTC 2.5" high flow cat dp and i have a leak and i have tried to tighten all 5 bolts and i cannot find this leak!!!

I just installed a XTC 2.5" high flow cat dp and i have a leak and i have tried to tighten all 5 bolts and i cannot find this leak!!! I have a leak and its super bad i live in Naperville so if anyone is near me and wants to help me figure it out please let me know

 

Thanks for the DIY info OBZ. Very cool Man!!!!!!!!!!

 

where are the install pics?

 

No prob bro! Hope it helps!
the first page?!?!

 

sorry. i was looking at it on the computer at work and i guess the pics were blocked. there there now on my personal computer

 

so do you need a gasket to connect the header to the enigine itself

 

yes. most headers come with a gasket, if not you can usually reuse your old one

 

Nice man I am glad I found this write up - Im installing a Vibrant Header/DP combo on my SS/SC tomorrow, hopefully this goes smoothly. Read all the previous posts so hopefully I can avoid some of those same problems others have been having. Thanks for posting this, you've taken my fears of conquering this away lol
