ok so ive gone to the police department and exhaust shops and talked to tons of people and i cant get a straight answer on hood stacks are the legal or illegal. i live in oregon but i know most states have a lot of similar laws when it comes to noise. can anyone help answer this question?

 

i know here in arizona you can run a hood stack but it cant be more than 18" tall and it has to turn away from the windsheild
i have have lots of highway patrol "friends"

 

awesome i hope the same rules apply here i really wanna run one because of the mods im gonna put on in the next month or two. do you or any on you know, know how or what stuff id have to change to run one?

 

cut a hole in your hood depending on what size pipe you wanna run.
just go from the downpipe straight up
i put one on my buddies 75 ford with a 12v in it, its fairly simple

 

from what i understand and what ive looked at im gonna have to flip the exhaust mani and turbo will this cause any problems with oil circulation in the turbo and can i flip the mani do the bolts line up?

 

not sure about the laws in your state but ive talked to local cops and state troopers and i got 3 friends that are inspectors and they say that here in texas the exhaust has to exit after the passenger compartment(cab) because of a risk breathing the exhaust and passing out so its not legal here.... and flipping the exhaust manifold wont cause any issues and the bolts will line up but you may have to get a longer oil return line for the turbo

 

If the police are intent on pulling you over - the hoodstack is going to give them more than enough reason. I cant imagine youd get away with in Oregon with the amount if tree huggers that are there.

 

I bet if you lived in a smaller town you will be fine, but if you go somewhere like Portland or Eugene they will complain. I had 5 in coming out before my back wheel and i got warned for that..

 

kewl ya i just moved to umatilla oregon a town of maybe 7000 people haha so i really doubt id have an issue. thanks for all the help if am i gonna notice any powergain or power loss with this mod

 

i know here in PA hood stacks are a no no...says it right in the book that the cops go buy. a very good friend of mine is a cop and i was reading thru his book looking for the same answer. exhaust must exit behind the cab of the truck. so i asked him if i do a hood stack is that all they can write me a ticket for. he said no they will probally throw in another ticket for obstruction of view...now i am right in the middle of 2 large cities. but as said before if its not too populated you will get away with it. there is a guy on here from PA running a hood stack and has no problems yet that i know of. but he is from a small town....
