well the main reason i am doing this is because i have a very limited time to get this item and i tried searching but i could not find what i was looking for, i just need to know if this ITR head will fit on my GSR , im sure it will but what modifications do i need to make ?
thx for the help

 

the reason im in search of a header is because turbo was taken off and i need to get some headers, found some stock gsr ones, but i saw a ITR header and was not much more expensive, but if ITR header needs adjustments then il just go with the gsr header

 

thanks for your pm's , <3 thx for the help

 

it should fit with no problems. U might need to do some adjusting on ur b-pipe and ur cat though.

 

It will bolt to the engine with no issues, however the cat will not bolt up. A muffler shop should be able to take care of this for a small fee though.
