I live in monmouth county. I have the 3 inch down pipe going to a 4 inch exhaust then into 5 inch stacks. No cat or muffler. The turbo whistles so loud with the straight pipes. You cant beat it. I havent got stoppes yet. And they dont emission test diesels here in NJ. Atleast not yet.

I received the exhaust kit last week. I had to cut the down pipe (what a biatch) and bang out the firewall (not bad at all). Got the exhaust installed and WOW, what a difference!!! Sounds great, nice rumble and sweet whistle from the turbo. Thanks for all the helpful info Guys!!!

I'd feel better about using less fuel, having a more efficient engine and lower emissions.
all the cat does on a diesel is make the engine work more. cats were designed for gassers, and Where the cat has to be placed on a diesel prevents it from having enough temperature to fully undergo catalysis and chemical reactions.
