Yea they will fit, with no mods to the pipes. just some mods to the can, and port extensions on the exhaust. I was thinking of making some port extensions to do this conversion, but would need $100 per set if you want them. The 2000 CDI box is just good insurance so you don't burn it up. You can run without it, and it will have to be rich, just like all of the aftermarket pipes are for vipers need fairly rich midrange jetting. I would recomend using the srx cdi, if mileage is a conceren. You will need to cut out the side panel above the right front shock tower.
