where to go in Maryland to get rear cats removed

[Marylandrauder]

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.

This is usually something you do yourself, you are going to have a nearly impossible time getting any shop to tamper with your cats, they can be fined big time for doing so. Just because your car may pass emissions without the extra cats, the factory installed them, so they have to stay on the car as far as legality is concerned.

I do believe that is a federal law that a business owner DOESN'T want to mess with. Fines, loss of their business license, etc. For a business to mess with CATS that is bad JU JU.

A hot rod shop will probably take them off.

I had my friend take my rear cats off, cut and welded up a new piece of pipe. If you want some better sound, get some Flowmaster 40 series mufflers and res-delete tips that Wes sells and make sure to have them extended out past the bumper by 1.2-1.5" to help lessen the interior drone.

Just start out with some Flowmaster 40 series mufflers and res-delete tips before thinking about the cats.

Remove all 4 factory cats, replace with 2 hi-flow cats and replace the mufflers w/ 18" Magnaflows.

My MM just passed NC inspection with the 2-instead-of-4-cats with no problems. Most bone-heads that work at the inspection stations just look to see if there are cats......... period.

i had mine done at a shop on pennsylvania ave in MD. i can pm you the number to the shop if you want, i dont want to advertise who did it being its illegal.

Has anyone installed an after market exhaust system, then gone back later and cut the rear cats? I'm trying to find out if the sound changes much by not having the cats.

I loved the sound I had with the mufflers deleted, but it was just a little too loud for my wife/boss. I'm wanting something that is both loud and rather obnoxious on the outside, but slightly muffled in the cabin. I'm back to running mufflers again. . . . . and honestly don't like it.

If cutting out the rear cats will get me closer, I'll do it. I just don't want to do it, if it doesn't make a noticeable difference.

Thanks

Yep this is true:up:
Do not goto a dealer to have this done as they will not do it , but there are alota barnyard mechs in MD and i'm sure they won't have a problem doing this for you.I know a couple in Northeast that will.

its not hard to just take off the hpipe and hollow them out yourself
