oooph big money man....they will have to cut your stock cats off the factory manifolds and weld them to the collector on the jbas....probably a 500-800 install depending on where you go plus the cost of the headers...

yea i have the headers i was told 550 by one place and another they said they couldn't give me a price because it could vary.

yeah the best thing to do would be have flanges welded to the jbas then have cats that are flanged....also have them flange straight pipes with no cats so you could unbolt the straight pipes and bolt in the cats when it comes time to smog....but if youre just doing headers b/c of a leak the cheapest install would be having them weld cats to the jbas. if you are looking for good gains do the flanged straight pipe thing...
