so here is my question...
from what i gather, when you install the header you remove the old manifold, bolt in the new header. then you cut the stock down pipe and bolt the down pipe extension piece that comes with the kit in place and clamp or weld that to where you cut off the stock down pipe.
my question is has anyone ever tried to make it so the header can bolt up to the stock downpipes flange? i really like to try and leave the stock pieces intact as much as possible.
here is a picture of what im trying to say. forgive my poor graphics.
does this make sense at all? is it possible to do with cutting off the ball flange or would one still have to attach the ball flange and weld the new flange that bolts up to the stock down pipe to the extension piece?
thanks,
rob.

You can do that, but make sure you add in a stainless steel braided flex joint in there. you will break your primary tubes otherwise...
We can hook you and anyone up with a pacesetter items (cheaper than online) just PM us what you would like (year/make/model/engine/ceramic or painted)

Sounds like you have it well planned out.

I might try that when my header gets here from turbo tech

the only thing would be if the header is longer than the stock manifold, which is pretty much a given since the stock manifold is only like 6-8 inches long. it was a good idea, but i dont think my idea will work.

performance gains from what, the header with the stock down pipe and cat or all the flange work im thinking of doing? i know there is know performance gain from the flanges, its an easy of instalation thing i like.
as for the header with the stock down pipe and cat, there is a performance gain to be had. granted, it could be a larger gain by changing the cat and everything, but if anything the shape and design of the runners should help with exhaust scavenging.

sorry, not buying it. a full exhaust setup (header, high flow/no cat, larger diameter mandrel bent pipe as straight as possible, and a very good flowing muffler) on these cars will gain you MAYBE 10 hp at the crank without any other work. its a nice idea, but sorry, a header attached to the stock pipe wont get you anything except a shiny looking hacked together exhaust setup.
JBO Stickers! Get yours today!
as soon as you swap down to the stock exhaust pipe, you are sacraficing any benfiits you may have gained. not to mention a high flow cat is one of the largest upgrades you can do on an exhaust.
Just go with 3.5" all the way back, thats what i have

Does the ball joint/knuckle on the header act as a flex-pipe so your engine can move independently?

If you don't have Motor mounts your engines going to flex when you step on the throttle. That Ball Joint isn't suppose to really move.. a braided flex pipe is best.
Grant you are SO SO SO wrong on this one...lol the ball joint is supposed to act like a flex, and yes the engine moving will cause it to move too much sometimes. HOWEVER, if everything is installed correctly(springs in right location), there should be no problems with leakage or anythign like that. I installed 2 pacesetters in one day, and after messign with them a bit, neither one has and leaks at all.
