exhaust straight pipe

does anyone know what nys laws require for the exhaust system on a 97. F250? I don't have a cat, and I would like to get rid of my muffler if I can.

also what does straight piping include? do I need to cut the pipe befor it goes over the rear axle or are the bends in the pipe not restrictive.

I plan on doing a 3in down pipe in the near future.

Well, your best bet is to contact either your DMV (department of motor vehicles) or maybe a few "reputible" shops that do smog/ exhaust work. If they're honest, they should be able to tell you what the laws are.

As for straight piping. It's a general term really. It refers to not having a cat or a muffler. Essentially, an uninhibited, free flowing exhaust straight from the turbo back.


Don't burn your bridges, you might have to cross them again in life.

Don't sugar coat things. It covers up the taste of real life.
