Exhaust Legality Question:

[Ben B.]

I want to shorten my exhaust system, which currently exits under my rear bumper. I want it to exit before the rearend with turn downs...would this be legal?

 

[Kyle Strong]

Don't see why not, I do it in my car and my truck is hacked off right behind the muffler, below the rear seat. Then again I'm not in PA, but I don't forsee any problems

Not sure of your state laws, but in Indiana, in passenger vehicles the tailpipe must exit the body, but on trucks it may exit under the bed, as long as it is behind the cab. Thats the exhaust law in Indiana

Inspection code says aslong as the exhaust goes out side of the body your fine.
