wat else would i need to install this perfectly??? jdm dc sport itr header, carsound 2.5" hi flo cat, skunk2 exhaust mega power??? is there anything else?? any poctures of a collector because i dont think i got one

 

it should be basically bolt-on...install piece by piece. dont forget the gaskets. the collector is at the end of the header, everyone has one (you can't not have one). the hardest part is breaking the bolts of the old exhaust

 

yea but what im confused about is that at the end of the header there is this triangle thing with three holes im guessing that is the collector or where the screws go in. but the cathlyic covnerter just has pipes not the triangle. im sorry i dont know what this triangle is called lol

 

damn you need more schooling lol.....the triangle thing is called a flange and doesnt go on the header, it goes on the cat--->b pipe

if your cat converter is just pipes you need to have the flanges welded on

header--->collector--->donut gasket--->2 hole flange--->cat--->3 hole flange w/ gasket--->b pipe w/ gasket--->axel back ... hope this helps but read some articles and you will begin to learn it
