I have the MBRP Duals T409 and love the sound, mine came with 12inch stainlees slash cut rolled tips to boot. Sounds great on both sides

Mike are you running with the MBRP muffler or the delete pipe? I'm contemplating doing a muffler delete...

Dennis at ITP Diesel has those clamps too for 9 bucks. I just bought a couple from him back in March or April for my truck, because I did the same thing. http://www.itpdiesel.com/store.php/p...s/Torca_EZSeal

Robin, the early '99's with auto's came with cats?

Wow, that sucks!

Once they begin emissions testing for diesels here in California, I'll be glad my Excursion and F250 came equipped without cats, because I have aftermarket exhausts on both of them.

I do feel sorry for the guys (like Nolan) with the ZF6 tranny's though, since they have cats.

I'm claiming ignorance on the cat if I ever live somewhere with emissions tests. It was gone when I bought the truck, so as far as I'm concerned it was never there to begin with

I wonder how they are going to wade through all of that? My truck is Canadian and had no cats.

Technically, if it came from the factory with a cat you have to leave it in.

I got some of those clamps for my exhaust from Diesel Manor. They ought to seal much better than the original u-bolts that came with my exhaust.

If your vehicle is located in any of these states you have to adhere to their rules regarding emmissions testing.....

If you live in a state like mine...Alabama...i can do whatever the heck i want to....

Exactly what Chase said. It's illegal to remove emissions equipment from any vehicle. So if a vehicle came with catalytic converters, they cannot be removed.

There are only two counties in Arizona that require emmissions testing. Maricopa County (greater Phoenix area) and Pima County (Tuscon area).

I don't live in either one.

What are the benefits to removing the cat and or muffler or are there any? Is it just the sound? I would like better performance but do not want to add any more noise, any suggestions?
