79 Rx7 Heat Exchanger Sound Reduction?
Installing an AEM UEGO, so I have some of my exhaust removed. What an absolute pain removing rusty exhaust bolts/nuts are.
My heat exchanger has some pretty significant rust holes in the bottom of it that are causing an exhaust leak.
How much louder would my exhaust become if I replaced the heat exchanger with a bit of straight pipe?
Thanks
Edit: I seem to have stock exhaust from the header back. So no air pump or thermal reactor, nor is the heat exchanger actually doing anything besides carrying exhaust.

There isn't a cat on the 79-80 cars. They had the absurd thermal reactor system thing, as far as I know. It looks like a cat on the outside, though the heat exchanger is much different on the inside.
It'll still have the stock muffler at the end. Its run a little with the rust holes in it and it doesn't seem too loud. I only want to replace the heat exchanger with pipe because it won't pass inspection like it is.

I thought it was a cat when I was going to remove it too, until I saw the inside of it. Did some research and found that picture. I couldn't find it mentioned anywhere in my Haynes manual either.
I'll probably just get a bit of pipe and replace it with that. Save some weight while I'm at it too.
If it ends up being too loud, can always pick up a presilencer then.

I have barely driven it any for how long I've owned it. Just an idea, but maybe I should have spent more time on getting it running versus rubber seals for doors and the like.
But, hey, at least it doesn't leak water as it's parked under a carport.
