if you ovalize the holes you can make it work, i dont know about bolting up to the rest of the exaust system though.

of you oval out the wholes in the 13b header it will bolt up the rest of the exhaust should mount up of be very close like an inch or 2 off (i dont think it would be) but if it is hangers are cheep at the exhaust shop and they will be alot cheeper then being a 12a header

buy the set up take it to the exhaust shop after you oval the holes and tell them to hang it for you if it wont bolt up..they shouldint charge more then 50 bucks (by me it would be like 20 bucks)

That is some ghettofabulous stuff. I wouldn't do it. Worst things worst trade you 13B header for a 12A one.

Not only will you have to cut a gap, you will have to cut the forward pipe and shorten it too.

ovalization would work, you would lose some performance, but i think it would do him temporarly until he gets a 12a header. i have seen and heard of people doing it, the differnce is very minimal. put a 13b header and a 12a one next to each other and you will see what i mean. ghetto fabulous..... yes, but it will work.

if the headers are the same length and same outlet, than yes.
if you buy that complete system im sure someone will trade you a 13b for a 12aa header in the for sale section.

What a waste of time. Just cut the flange. You're making life too complicated.
