The pipes they sent you are for the y pipe and should be 2.5". Also, there have been tons of people to include myself that have had to dent the head tube in order to get it to fit on the drivers side where the steering rod is.

Are you coating all 3 pieces and if so, what did they (Jet Hot) quote you? I need the info for our SLP header GP.

Thanks a million...

Is it really necissary to coat stainless steel headers?

Unless you want them to turn a nice shade of rusty brown, then no.

I was told the pipes they give you in the dual cat kits are a stock sized pipe. The dual cat headpipes are 2-1/4 factory. The y-pipe for single cats is larger because of how restrictive the factory set-up is. A larger y-pipe is necessary because the single cat design is still a restrictive set-up, but its too $$$$$ to convert to dual cats. I guess the companies making dual cat headers feel the pipe sizes are adequate.

BTW, it wouldnt make much sense to have a pipe come off at 2-1/2" then go to 2-1/4 cats, then merge into a 3-inch pipe. Bit of a rollercoster ride
