Who has reinstalled a cat after running full exhaust
I love my car after owning it for 7 years but I would like like it to be less in 2 ways.
Less smelly and a little more quiet,
(every cop for 3 blocks to knows I,m there)
I would like to hear from anyone who has run a full exhaust that installed a cat and what their experiences are,thanks,Carl.

The smell, I can understand...
But you're running a Greddy SP. I'm running the RB duals on an open, and it is very quiet unless I get on it. Everyone I talk to says I have the best sounding exhaust they've ever heard. I wish I could hear it at WOT from the back; too bad noone else is allowed to drive it

Well I heard a resonated midpipe at idle and it gave me the idea....the Rx7 store sells them for $250 their hi flow cats $100 more.
Someone chime in who has fitted a high flow cat to a open exhaust and tell me what if it will hit my goals of getting rid of the smell and quieting things down a bit.

I have a SS downpipe (I don't know which brand), a 5" SS cat (again, don't know the brand), and an HKS Superdragger catback. With the cat installed the car is noticeably quieter, the smell has been reduced to almost non existant, and I don't have boost creep issues .

SMB sells a mid pipe that has both a metal cat and a muffler in it. I just installed mine after running the RX7 store mid pipe with the Magnaflow muffler. The performance and noise levels are similar with less stink.
I also have a mid pipe that I had installed a metal cat onto (w/o a muffler or resonator). That definitely killed most of the stink and flowed almost identically to the straight mid pipe according to the butt dyno.
I also tried a Bonez high flow cat. Performance did suffer slightly with that setup according to the butt dyno. Spool up with a bit slower but it was quieter and smelled much less. After running an open exhaust for so long, the most similar setup for me was to run the SMB.

Only on the butt dyno.
Meaning I never dyno'ed it. Going by how it felt on the street.
It feels close enough that I didn't notice a big difference on my setup. I'm running ~10 PSI on 99 twins with a streetport fwiw. I don't know your setup so I can't say that your results will be the same but I have been very satisfied with all of the above exhaust setups for different reasons.

I TOTALLY needed to read this. My wife won't RIDE in my RX7 because of the noise and especially the smell. Not having an airpump, I had read mixed reviews on adding a cat. I need to get a metallic cat and move on.

BTW, the Greddy SP is for sale, too. As David said, the Greddy SP is about as quiet an exhaust as you can get.
