3 questions.....

Shouldnt the header go from the 2 pipes from the engine to 1 pipe into the cat..? Where would the two exit pipe connect to?

The road race style that you linked is to run a true dual exhaust. That keeps the exhaust running individually all the way back. You would need to look into getting the street header in which the two runners merge into one at the flange, so you can mount to the cat.

Crap.. I dnt have a tru dual exhaust -_- i guess im gunna have to fabricate an adapter pipe and weld it to the exit and then to the magnaflow hi flo cat and then to the exhaust

Im not sure but this might be single pipe exit if so ill prob get this OBX header:http://item.mobileweb.ebay.com/viewi...id=54759072992

Yes that is a street header there.

Idk im not sure it kinda looks like the exit part splits into two but maybe it ia a single pipe im gunna ask the seller but if it is then thats perfect i jus need 65$ more to get my magnaflow hi flo cat and im good to go

Also what about this? Its like $40 cheaper and its a single pipe exit, the only thing is in the discription it says its got 2" tubing to 2.5 collector.. Idk what a collector is but isnt 2" the same as the oem exhaust manifold or smaller..?

[BoostedFC]

You didn't link anything. But the 2" is for the runners (the pipes to each port ) & the collector is 2 1/2" ( the pipe where the two runners merge together which is why it's called a collector ). You OEM manifold is a heavy non flowing casting & the header is a tubular individual runner performance part designed to flow better.

Wow im an idiot lol but this is it: http://item.mobileweb.ebay.com/viewi...id=22554621866

It's the same basic header as the 2nd one you linked just different exterior coating.
