1st my zzp header/downpipe combo did not come with a gasget for the manifold to engine was it supposed to.. should i use the old one or buy new one...also do i need to torque the bolts on headers down to a specific pressure or just get them tight..

 

reuse the old one if its not torn. it has a metal ring, so if its intact, its fine.

 

Your able to reuse the stock gasket.Make sure all the bolts are in and started by handbefore tightening. Tighten the header first from the center and work your way to the ends. Enjoy

That should answer all ur questions.

....the search is ur friend.....

 

yah iv read that thing like over 4 times..doesnt say anything about a zzp header coming with or without a gasket does it

 

comes with header-dp gasket, and dp-catback gasket.

no engine-header gasket.

either buy a new one....like $10-15
or if the old one is still in good shape, just reuse it.

 

it doesn't come with the gasket. like said, you can reuse the stock one unless it looks damaged.

as far as torquing the bolts, the header bolts only need to be torqued to 10 ft/lbs. if you don't have a torque wrench, or aren't familiar with torque ratings, 10 ft/lbs is not a lot at all. basically you want them to be snug, and that's it. \

 

Well that link was for the question that u had about tightening down the nuts on the studs that hold the header to the block. Gives u the torque specs and the pattern. U could of found out about the gasket if u did a search also because it has been discussed SEVERAL times.

i did search but i wanted to know about the zzp header specific...when i did it i got nothing i even re read the 90 page group buy thread on the product...so believe me i searched

 

On page 54 of the group buy thread. All i did was find the thread and then did a search within the thread and there it was.

thanks man..you proved your point like 2 responses ago..your saying this in a kinda dick way...

 

It takes a minute for these things to update, don't take it personal.....

at least you weren't worried that the gasket primaries are smaller than the new pipe, since they are the same size as the heads.....

 

well i didnt think about that.ahahh and i already dremeld the gasket wholes to fit to the headers..oh well its already in so..im getting a flapping sound i hope its not from my dremel work....im hoping its the gasket from dp to exhaust..it was 2 big and buckled up when on the studs and i just clamped it down in there anyways..
