Just like the title says. I did a search came up with nothing. My car has a 2" exhaust pipe from the header back. Just tring to see if thats the stock size or was it upgraded. All the pipe looks fresh for the most part so it was replaced.

 

stock pipe is tiny, like 1 1/4 or 1 1/2

 

cool thanks good to know need to go bigger piping

 

Who is on here with a stock 1991 Honda CRX in 2022???????????
