Default Straight Piping Legallity Throughout the US

Hey, I'm just curious about where straight piping is legal or not legal in the US. I know in California it's illegal, but I live in a county which is a rural/remote area and just about everybody doesn't care and/or has a truck anyway - the sheriffs around here give tickets for rice burner mufflers and not straight piped trucks haha...

What makes it illegal anyway? Some kind of retarded emissions deal? Noise? Either way it's stupid; more fuel is used because of the cat and clogged up **** that can't escape. There isn't really any added noise with diesels w/ straight pipes , just a more noticeable whistle of the turbo (Which is awesome anyway...)

its illegal everywhere on passenger vehicles, if its a big enough truck you get exemptions for pollution but still have to maintain a certain noise level, the thing is enforcement, in california you have to go get a emissions check, here in iowa we don't even have vehicle inspections at all, around here they will write you a noise ticket if you have no muffler but as long as you got one your good, I had them check my mustang many times when they were pulling me over to hassle me and give me 6a ticket for slicks, the main reason why shops won't do it is because last I knew it was a $10,000 fine from the EPA.

Jesse James got in HUGE trouble with the EPA because of his exhaust systems on his bikes.

Why people put straight pipes on trucks is beyond me. I guess if you like your truck sounding like a rusted out pos farm truck then by all means. But it just has no tone or throaty growl, its just loud and crappy.

maybe for mud truck racing or somthing, I sure wouldn't want to listen to it on the way to work everyday, if I was going that route I would probably just go with zoomies lol.

It's not legal, but it's not enforced here in Bartow County, Ga. We don't even have emissions inspections yet. There are quite a few people here that get a car/truck and the first thing they do is rip off everything from the header/manifold back and put in straight pipes. It drives me insane. It's loud, obnoxious and you know there is no way they can hear what the person sitting next to them is saying. When I had my truck I just put some Edelbrock headers and cat forward system, High flow Catalytic Converter, and Magnaflow cat back exhaust. That was one of the best sounding trucks around. I got complimented on it wherever I went.

i'm thinking about going to a straightpipe on my '02 jetta tdi. makes it sound much better IMO than a stock annoying diesel exhaust note.

here's what it'll sound like if i do it... http://www.youtube.com/watch?v=83ife8p-nvU

Yeah, on gas vehicles. I don't like it when people straight pipe gas (I was somewhat pointing toward diesel in my post); diesels sound great with it though.

On another note, my M35A2's (military 6x6) are straight piped, but being an older large military vehicle they are exempt.

Ok why would you really want to??ALL engines diesel or gas need a bit of back pressure in the exhaust to run right..straight pipes just wont build enough back pressure not to mention how bad they sound diesel included...I mean to much flow is as bad as not enough...if you look inside the headers they run on drag cars youll see a cone on the inside thats designed to maintain a small amount of back pressure..its like running a tuned pipe on a nitro engine the right length and diameter and it helps the engine rev higher and put out more power...just wonderin

There is a way to have straight pipes an have a "muffler". Just cut a square section out of your muffler, cut the baffles out, weld the square section back in and grind down the welds and paint it. That way you still have a "muffler" but have a sound that is more like straight pipes. They would never know....
