Pa exhaust ?????
Hey there fellow Pa'ers. I'm putting a new dual exhaust on my 78 shortbed. I had it made at a parts store.(saved a couple bucks) Everything lines up good until the sections after the mufflers.The arch over the axle is too high then too low, so I was thinking of bringing it out in front of the rear wheels just behind the cab. Is this still legal in our great state or have they foiled this plan for me.
Several years ago I seem to remember someone told me it had to exit the rear of the truck. I can probably get the pipes fixed right, but I could have it done right now if I bring it out the side in front of the wheels. Anyone know for sure? |
before i put my stacks on, i had the exhaust going out the side in front of the rear wheel, no problem. i believe the law is that the exhaust must be routed either behind the cab or above. i haven't had any problems inspecting with my exhaust setups, but my truck is diesel. i don't think you would have a problem as long as the exhaust is behind the cab.

From the vehicle code found on the PA DMV website. There could be more but I gotta get back to work! Here's the website:
http://www.dmv.state.pa.us/vehicle_code/index.shtml § 4523. Exhaust systems, mufflers and noise control. (a) Compliance with established sound levels.--Every motor vehicle operated on a highway shall be constructed, equipped, maintained and operated so as not to exceed the sound level for the vehicle as prescribed in regulations promulgated by the department. The test procedures and instrumentation to be utilized shall also be established by regulation. (b) Compliance with exhaust requirements.--In addition to any requirements established under sections 4531 (relating to emission control systems) and 4532 (relating to smoke control for diesel-powered motor vehicles), every motor vehicle shall be constructed, equipped, maintained and operated so as to prevent engine exhaust gases from penetrating and collecting in any part of the vehicle occupied by the driver or passengers.

(c) Limitation on sale and operation of vehicles with altered systems.--No person shall knowingly sell or operate a vehicle whose emission control system has been disabled, changed or altered from its original design specifications, except for in-kind replacement of system components and added components which are designed to improve emissions. |

WOW!!! I gotta headache after reading all that. Thats some detective work 2000. The section about HEAVY trucks sounds good but I don't think they would consider an F150 a heavy truck. I'm going to call the guy who does my inspections to see what he says too. You have one hell of a job if you could look all that up and post it. Congrats!

It didn't take much. I have a few websites set as my favorites that pertain to vehicle codes, not to mention google is the greatest! When I moved here from AZ, I read up on inspection laws until I couldn't take it anymore (my truck barely meets the bumper height restriction)....

I'm sitting here with my buddy who has an inspection station. He said as long as it's past the cab it's okay.
|
anywhere past the cab and 3 or 5 inches (not sure)from the rear tire
|
Past the cab is what my guy said too. After looking at it for while I think I'm just going to go straight out the back. The "tail pipes" the made our way wrong, but I have a couple pieces of some what straight pipe I can use to get me back there. It's a shortbed 4x4 and both pipes run down the passenger side then branch off after the mufflers. It would be too much work to get back to the drivers side around the drive shaft. BTW anybody looking to put a little sound from under your truck I highly recomend the Cherry bomb Turbo II mufflers. They have a great sound but not like your running straight out of the block with them. I think my neighbors will appreciate it when I get home late at night or leave early in the morning since I've been running with just 1 rotted exhaust pipe and 1 missing all together for about 3 months now. Thanks for the assistance.

I had an issue last year with exhaust, supposedly, they had changed the law regarding certain things, such as the "so long as it's past the cab" thing. I had duals that dumped out under the bed, and it "wasn't legal". Had to get it out from underneath. I dunno if that's a legit thing or not, perhaps they were just giving me the run around, but they said it was illegal now.

I'm sure it changes with each station. I've taken my truck to some places and they tell me I needed mud flaps on the front tires or some other bogus thing and that he wouldn't pass me. I go to another place and they'd shake their heads when I mentioned it and would pass me. Seems like the inspection process is kind of a joke if you ask me. Then again, I'm coming from a state (AZ) where they don't do inspections. As long as you pass emissions out there, you're fine.

I really wish PA would join the other states that DON'T have inspection, but it generates too much money for the state in taxes, fines, and fees...I'm pretty sure it'll never go away. Pat |
Money talks and B.S. is everywhere. I thinks in Jesters case if the exhaust exited from the side it would be O.K. But as silver bullet and PatsPOS say it depends on the guy who holds all those little magic stickers. I've been to all kinds over the years and I found a guy who tells it to me straight and understands Pa's "crazy" inspection and emissions "laws". I agree they are all here to stay...........forever.

Here's another one on the subject of emissions. I understand you can get an exemption for having under 5000 miles since the last test, however, does this still apply if you are a new owner of a vehicle with less than 5000 miles since the last emissions test?

i have a dual exhaust on my truck that is only custom AFTER the o2 sensor. on each side, it goes cutout, highflow cat, 8" glasspack. then it runs out the back to some big tips. my truck gets dyno tested for emmissions, and my mechanic says as far as sight goes, as long as theres a cat and a muffler, its cool by him. doesnt matter what kind of cat and muffler they are.
when i finally put on my long tube headers, i wanna get it set up so i can have my o2 sensors right after the collectors, then do electric cutouts inside the frame rails, and then have the pipe bent up to go over to the outside of the frame rail (running tight and parallel to the frame rail), then do cat, glasspack, and have it bent out 45 degrees with my big tips right before the tires. that way i can eliminate a bunch of extra pipe and make room for a big hitch in the back. |
