Hey guys i bought a pair of used B&B headers, just wondering the best place to get some high flow cats and also have any of you guys had a problem with the check engine light after installing the high flow cats and headers..thanks!

Mine are from B&B and yes you will throw codes (P0420 and P0430 I think) But it will not affect the cars performance. It just a code telling you your cats aren't as efficient...
A tune or O2 eliminators (like posted in another thread) will take care of that.

ok yea my b&b headers look like they have stock cats connected to them, i am not positive but i think so, im going to try and post a picture
Those are tri-y headers. They are the old style B&B with high flow cats attached. Look at the faq as those are the EXACT headers used in the write up.

i had a feeling they were the old style hopefully i wont have any problems with fitting them to my LS2 and they are definitly high flow cats?

You might want to look inside and see if there is anything left of the cat and not a hole burned through it.

No problems, they will bolt right up.
Heavy isn't kidding, my understanding is this is why they went away from the Gen 1's.

You might want to use the search feature.
You will find a lot of useful information on the original Billy Boat headers.
