i just got the dc sports jdm 4-1 header with the 2.5" collector. i also got a test pipe with a 2.5" flange on it. what else do i need to install this? is it a easy job i was thinking about doing it myself. ive done everything else on my car just dont know how hard a header is to install. thanks for any help!

 

Exhaust manifold gasket.

 

how much are they and where can i get them? i was also told i needed a donut gasket for the collector and testpipe connection to form a seal. is that true? and do you know how much torque the headers require to the block and to the cat or test pipe?
