not sure if magnaflow would fit. that would require some jigging. dont want to deal with that.

my understanding was that the aftermarket headers shorten the exhaust tract. once in the first 2 O2s plug in but the 2nd set has no place to go. then when i go to install the cats the second set of O2s would plug up in them.

i didnt know this would require some wielding of the pipes or extending of the O2s. damn this is going to be a lot of work
LoL, I had no idea you had other replies!

But anyways, everything you need can be ordered from vibrant performance from adapter pipes to cats to sensor bungs. But I'd rather stick to magnaflow cats.

Proven to pass. I've heard stories with Random Tech cats where the CEL light still comes on.

But the headers should be a direct swap with the stock ones and they shouldnt alter the position of the pipes.

The only welding that's needed is to fit new cats into the exhaust as the stock system has the cats integrated into the headers.

Give a good shop the better part of a day to get it done for you.
