Stock catback HP limit with boost?
I'm trying to find out how much HP one can make with a stock catback (and test pipe). I own a Js 70RS, but don't want to use it if I don't have to because its extremely "droney". I was thinking it would quiet down with a turbo setup and would only use it in that case. Has anyone found out how much the stock catback is rated for both for turbo and supercharger applications?

Your question doesn't really make sense. "X" exhaust isn't rated at a set HP. Your only measure is going to be how much one is restricting you. For example, the first reply here. Maybe he got to his HP goal on a stock exhaust, does that still mean it isn't a restriction? Would he have gained power from swapping exhaust?

I made 401 with stock exhaust and 70mm tp

To clarify my question, I'm looking at what the highest HP someone has made with stock exhaust and a test pipe. I understand that exhausts are not rated for HP values, although I do know that stock is relatively restrictive.

Good to know that turbo quiets the exhaust a bit.

I'm sure I have seen countless amount of people in the upper 400s with the stock exhaust. As long as you have a test pipe the stock catback exhaust should not be a huge issue until over 500whp. At the 400ish who level I would think a full 3inch exhaust would be good for about 10-15whp over the stock catback exhaust.
