do u know what size the bbk headers are? so i know what collector to buy. i need to know the if the bbk headers are 2-3inch and what the stock pipe inches are so i can buy the right one. i bought the 3inch but i now know that i need a 2 bolt flange instead of 3 so i have to order another 1.

thanks craby i know its a lot of stuff i am asking in this thread but i dropped the tranny only to find out all this stuff that is leaking/wrong with my car that i never knew about so bare with me. i still have to find this leak that is in the back of the engine passenger side. all new valve gaskets that i rechecked 3 times. Upon further inspection, i did find out that my rear main seal was leaking which i just replaced so that might of been the leak. my intake manifold dosent seem to be leaking the rtv is still intact.

 

lol, well if theres another spot back there that oil can come from i dont know about it, if your oil pressure switch is there they have been known to fail and leak.

 

i might just re-do my intake manifold just to be sure its not that.

 

i found out that my exhaust manifold gasket was burning and that was all the smoke. i bought brand new headers they are racing stainless steel headers. the headers have a 4inch diameter and i want to connect it to my existing 3inch piping but i cant seem to find any 4inch to 3 inch piping. could i weld the 4inch piping on to a 3inch? this is the header i bought http://www.protuninglab.com/hds-cc93...id=87012368578

 

that shows a 3 inch y piping. so the pipe inside diameter is 4 inches?

 

the guy at pepboys told me it was 4inches but im thinking its 3inch because of what i saw on the site but im not certain until i measure it myself.

 

it says header exhaust manifold? thats a shorty isn't it. on the outlet it says 2.5 which is stock crossover i believe. wonder if the picture is wrong.

 

it looks just like long tubes to be honest. i have no idea tomorrow i will measure it i bought 3 inch pipe so we will see. is flex pipe known to leak?
