Is there any possible way to pass emissions with an off road Y-Pipe? or is there any way that a off road Y-Pipe can be cut to fit a cat? Just looking because I bought the Y-Pipe thinking it was a legal one and got high flow cat as well!!!

 

The difference between a straight pipe and hi flow cat isnt even worth effort. Just stick the cat on and dont worry about it. Cat eliminators are a scam anyway, just get some exhaust pipe the length and diameter you need and your golden. I had a straight pipe on my V6 Fiero, and parts cost me $6. I have a cat on the LT1 Fiero now due to emmisions.


And no, you wont pass w/out a cat.
