exhaust

[TNStroKE]

i know on gas burners in tennessee you dont have to have an exhaust as long as you have a cat. is it the same for diesels? becuase i took my exhaust off last night and am just runnin a cat and im gonna get it shot out the side before the tire if this is the case. will i run into any back pressure problems?

i don't have a cat or muffler i have straight 4in and no back pressure problems so you should be good to go you should stack it

Prior to 03 there are no emissions requirements on diesels...

Depending on where you're at around here though, depends on wether or not they know that seems like.

Hollow out your cat, and push it out somewhere behind the cab and you should be good.

Yes there is too Tom, in all emission testing counties. They test everything under 10,500 lbs GVR, so Superduties are exempt. They plug in and test the OBD2 on 03 and up and they smoke test on 02 and earlier. They even have a new attachment now so they can smoke test trucks with stacks.

I removed the cat, then just took the heat shield that goes between the cat & the floorboard and welded it upside-down. Now when he looks under the truck with the mirror, he sees the shield & thinks it is the cat.

I meant, that on my 02, I'm not federally required to have a cat.

Think the county laws are more based on what the truck came with, needs to be seen.

Up here in hicktown there's no testing though lol

Robbie where is the checking station where they told you we don't need cats?
