Hey Scotty I watched one of your videos and you mention a car that is over 25 years old it’s exempt from emissions testing. Now my CivicR ( and the people who thinks my CivicR is a Type R, heck nah. I don’t own a Type R. It’s a 02 sedan with a EP3 Type R engine) today is 20 years old. It was manufactured on April of 2002. I calculated on April of 2028 it gonna be 25 years old. My question is, can I cat delete and straight pipe it when it reaches 25 years old? Here in Va they do emission testing when renewing your registration but on different counties.

is it exempt from noise law?


he's asking about a "cat delete"


@jack62 I thought "straight pipe" meant: just pipes from exhaust manifold backwards. No cats. No mufflers. The straight piped cars I've seen make a huge racket.


Me too. But I learned the hard way that we can't assume that everyone on this forum knows exactly what these terms mean
.
When I reread his post for the 2nd time I noticed he asked:
My question is, can I cat delete and straight pipe it when it reaches 25 years old?


Perhaps.
well if the cat works fine I would just leave it. I don't think you'll notice any performance boost, and you'll just have a constant check engine light. And yeah it's against federal law.

You can do what you want, but it's only a 4-banger and will sound like absolute garbage. You'll probably get tickets, too. If you have neighbors, they really won't like you. An apartment I rented a few years ago fronted on a busy street during the day, but you could hear whispers at night. Some moron in a Honda that was straight-piped would drive by almost every night, pedal to the metal and wake my wife and I up -we were facing the street. 


the sound reminds me of a chainsaw


Yeah, a very annoying chainsaw, we'd wake up from a dead sleep every night that that he did it. Thankfully we don't live in that apartment anymore, lol.
