Is it legal?

I was wondering if anyone else knew that, well at least in my county in Illinois, that it isnt street legal to have straight pipes running all the way to the rear of my Monte. I have to put a y pipe in place for it to be up to code. Bullstuff

I dont think it is illegal over here in detroit. I have true duals on my vette.

Detroit is perfectly legal.

Yeah ok affordable Horsepower with a Monte Carlo that you can work on, or a Porche, where all the parts are 5X the cost of a regular part, you have to import some parts, pay people to do them, and illogical engineering some times.
