Hey guys. Probably a stupid question, but I’ll ask anyway.
I’m in PA and have to pass emissions every year. What can I do to my exhaust to get some better sound and still pass the emissions testing?

22 Forte GT.
Thanks.

Always best to check local laws, ask your smog tech he will tell you.

Don't touch the cats, anything else exhaust wise should be fair game from an emissions standpoint

You are totally safe with a cat back exhaust. You can even get away with headers, down pipe and a high flow catalytic converter. Upstream before cat and downstream after cat O2 sensors need to present and working. Car can't have any codes.

Thanks guys.

I remember having to do emissions, no longer though here lol

I did kind of forget that since the car is a 22 model, I am exempt from emissions for 3 or 4 years. Hmmm.

They stopped doing emissions checks here a few years ago.

Honestly OBD 2 cars run better with emissions in place. I was big into the custom compact scene in the late 90's early 2000's. I ran an
emissions legal header, moved close coupled cat with a custom down pipe to under the car with a high flow cat. Finished this off with a cat back exhaust. Setup made a big difference and the car passed emissions and had no codes.

I wouldn't run my Forte without it, my Corolla on the other hand it makes no difference but that's a different story lol

Funny how that works, I had an 80 Toyota pickup with a high compression 22r, big cam, Weber carb no EGR, no cat and a tri-Y header... it passed just fine but failed visual. My 100% stock 84 nissan pickup couldn’t pass out the tailpipe if it had a gun held to its head.

It took at least 25 years for most car manufacturers to figure out how to get back the power lost with emissions. Then they ended up making more power because of them.

I honestly don't know, but I don't think, that my Corolla would pass today, but we haven't had emissions testing here for a few years now.
