I am seriously considering this header. I have an 2.2L motor. I have a 2-1/4 catback already. It seems a lot better than pacesetter as far as quality. Would this header hurt my gas milage? I don`t like 1-2 MPG decrease but anymore than that I won`t be happy. Has anyone tryed this header. And if so did you use the header wrap. I have the Weapon R intake. So I might use header wrap. This header had 1-3/4 primaries with a true merge 2-1/2 collector. I think it is designed more for the 2.0L SC. But what do you guys think.

 

I dont know if it will fit and also there is some threads on here abouth people having problems with getting their header after paying for them.

 

it will work it will fit the 2.2 2.4 and 2.0

 

What do you mean? I'd like to see some facts or something that makes this a valid point. Just kind of an interesting comment.

 

because it traps in heat and slowly breaks down the header material over time

not worth it.

 

Be very cautious of SCDyne. I personally know one SS\SC owner who paid for his awhile ago and he is still getting the run around. He has not received it "YET".

 

i know of an entire redline community who received absolutely shitty headers, not even usable.

BUT I think hes gotten those problems fixed, atleast I hope.

 

doubt it, besides which if it's the same design it's still ****

hold off for a better design or look into getting one built for yourself, it'll save you the headaches this brand will bring

 

What's a better alternative for preventing heat from entering the engine bay?

 

Yep still waiting. I am hoping for this week

 

an actual thermal coating

what ninja is referring to is that you will be keeping heat in the metals without escape much longer than originally intended. that will increase the stresses on the materials and can cause premature failure. I've seen some that self destructed from wrap, and some that were fine, so use at your own risk, but I dont' think I'd roll the dice.

thermal coating isn't nearly as drastic. you can also find a way to keep the factory heat shield down there to deflect heat away from the engine bay toward the ground and back, just an idea.

 

The impression i was under is that header wrap allows the exhaust gas to stay hotter and expel faster. I can see how this would be hard on the header but what about a low degree header wrap? Like a 1000 degree wrap. Or is it just that the heat stays within the header so much longer that causes problems?

 

bingo

sure you want heat retention for scavaging and such, but too much heat on the materials is no good over time. now if it will help direct the heat out but still dissipate then it's good, but if it just holds it in, you get what I mentioned earlier

 

the scdyne headers looked fixed to me my buddy riceeater just put the new one on his car and it loked good to me,2.2 2.4 and 2.0 are basically all the same motor different internals on each the 2.2 and the 2.0 are exactly the same but the 2.0 has beefed up internals and its destroked from 2.2 to 2.0 so any header for the 2.0 WILL work for the 2.2

 

sure will, I"m running a 2.0 manifold right now since I got it next to free and needed a quick fix for something.

rice eater (bryan) has one of the "fixed" ones? I'll have to look on the "other" forum and see if he put pics up. if he's actually running one I'm going to assume it's at least a decent improvement over the original release.

 

yeah the other one i think was a tog and i sucked bad,in gettin the old header and rewelding it other than that its all good.....scdyne tog same company,yeah his car is up and running and its badddddddd

 

i work at pacesetter , and here is pics of 2 header that came back for warranty , that i declined because they were wraped

if you look closely at them you can see dots , and where the lines from the wrap , ive seen headers come back where the metal moved like rubber

ive got 1 more header from a ohv cavalier that is worse than these 2 , that i need pics of

for give them being huge

 

Wow those look in pretty rough shape too. How old were they? What material were they made of? Were they ceramic coated? Thanks for the info.

 

So is the moral of this thread the SCDyne header is ****? That's what I've gathered...

 

damn those headers are rough looking, hope mine doesn't crack anywhere!

p.s. - hook me up with a job at Pacesetter

 

16 gauge mild steel , not ceramic coated

and id say 4months to no more than 1 year , and not in road salt climates

 

Ok, thanks. I am really worried now. haha I need to eliminate some of the temps in the engine bay so my ice box and supercharger don't heat up so much. I bought a roll of cheap header wrap but now I don't know if I want to use it on my TOG header. I may and then just buy a new header later. Anyways, thanks for the help.

 

i would use the header wrap on the parts you want to keep from getting into , the lines , ice box

ceramic coating really helps alot with temps , as does a header that has less bends in it

while at sema last year , we were next to a guy that made and sold header wrap , he wasnt aware that alot of header companies void their warranty when wrap was used , he said he would add that it might and to checkwith the manufacture of the header

and he did agree that wraping parts you want to keep heat out of would work as well
