I have an 04 Marauder and I live in Gaithersburg MD., Iwant to know where I can go to get the rear cats removed, do I have them gut mine out and reinstall them or just have them put in a pipe, I also want to put some dynomax ultra flow mufflers or should I just put in a straight pipe. I have read of others replacing the cats near the manifold and putting in high flow cats do these go in the same place, if you remove the 4 cats will this throw a code and you cant pass emissions, also are the resonator tips on the marauders restrictive, as I have seen on this site resonator delete tips, do the resonators just quiet the sound down without hurting power, this is a stock engine and I am not going to do a tune as I need the car to start when I drive it, I have read of people with the x-cal2 tune going out in the morning and the car not starting, any advice will be greatly appreciated, I will also be at the Marauder get together in June at Safford Lincoln Mercury in the Montgomery Autopark off Route 29 in Silver Spring MD.
