exhaust leak only when AC is on?
hey, I just recently got the 40th anniversary rx8 #451, but when I turn on the AC I can smell exhaust.. and when I walk and visit my father he says he can smell exhaust on my shirt. the catalytic converter is gutted, the guy who sold me it said it was removed but it was gutted. I went to an exhaust shop and the guy said he didn't hear/smell an exhaust leak, and if anything since the converter was gutted it could have been that just somehow leaking into the cabin. any ideas/solutions? also, I hope this is the right forum to post my issue, let me know if it isn't..
also thought of just getting a custom mid-pipe from the shop too.
also, there is a rattle in the car only when it's idling with the AC, and I've read that it's possibly the motor mounts...
thanks in advance!
also, it's a 2008 with 67k miles on it, everything seems good, heavy duty spark plugs recently replaced, and a small oil leak i plan to get fixed sometime soon, not serious though, will keep an eye on the oil

I mean, by all means confirm that, you can feel for a leak if you can get under the car at all. That cat to midpipe joint is particularly it takes a special Mazda sealing ring. Perhaps the previous owner didn't do it properly. If you see bits of aluminum paper gasket in there, that's an automatic leak.

Did you open up and inspect/install a new cabin filter in the ventilation system (remove the passenger dash glovebox door for access to it)? You can get one with a carbon filter layer, though that will only help so much for so long.
I suppose it might make too much sense to have a cat converter installed instead. Where do you live?

did not.. but I will do so now uhh I live on the west side of iowa almost into nebraska
don't think they car about midpipe's and straight pipes anyways.. there's a ton of honda civics and big trucks that get straight piped so if I keep the muffler i think I'll be okay

there is a loose gasket that I'm gonna buy new parts for the "cat" so I'm gonna order those parts!
although there's a slight oil leak that I'm gonna go and get it checked out.. I know a guy that's torn apart and rebuilt rotary engines so he'll hopefully help me out 😁
