sure this has been asked if so im sorry buttttt does anyone have a chart or something that shows what exhaust manifolds will interchange between what motors?? Say like will the ls motor from a gto fit a VORTEC motor from a 2005 sierra 4,8??

 

Yes it will fit the motor.

 

ah cool thanks for the reply!!! Reason i asked is cause im seeing these gto's and g8's with turbo kits and the look like flipped truck manifolds to me with an up pipe comming off the manifold to the turbo. then as i read some more it confirmed thats what they were lol sooo i just gonna flip em and Order the up pipe adapter and save money ------- alot of money

 

Ya, allot of the GTO guys just take truck manifolds and flip them. The truck manifolds are angled a bit different so it works better for them.

 

OH ok gotcha just seems like a cheaper and more practical way to go to me and just run the down pipe out the side with a electric cutout for the track ill post pics when i start fabricating and thanks 03sierraslt
