I'm about to have a new Warp y-pipe, Magnaflow cat, and Budget b-pipe all SS installed. I wanted to know if I'm better off having my shop weld everything together (not sure if they use SS for the welds) or bolt it all together? With welding I'm afraid that it might compromise the SS and accelerate rusting at the welds. With bolting everything together will I risk exhaust leaks from gaskets? Any advice is appreciated.

 

Um if you weld everything, what happens if you need to take off anything off?

 

I agree. You can weld y-pipe w/ cat like stock, but b-pipe, what if you want a catback later? Do you have a way of passing inspection? I've had bolt-on parts for years and never had a gasket leaked.

 

RHMax That is what I wanted to hear. I actually have a cat back but would like to bolt everything together that way I can change out parts easier if need be. I'm also going to keep my stock cat for the future. They run 650.00 at Courtesy. I bought a Magnaflow SS but I heard they will not last like the stock. Mine is all rusted so I want it changed.
