I've had my '82 GS for some 12 odd years. I have the RB header/Presilencer/Muffler mod in place and it's working well. but i guess i can't leave well enough alone a now would like to get it closer to stock - as in replacing the Pre-Silencer with a CAT. however, I have obviously done away with the air pump and associated parts. Does anyone have a header/cat setup that doesn't require going completely back to stock? I really don't want to first find- then reinstall all that..uhh stuff.

I hear that the new high flow cats dont require an air pump.

You should talk to your locoal muffler-oligist.

Sure, i'd sell what i'm not using, but ideally, i'm gonna keep most of it in... just would like to find a cat that would bolt to the RB Header. but if i gotta get a different header/cat setup...

Maybe he doesn't like the smell?

Good question! i must be getting mellow(er) as i turn 40 eh? - I did most of the mods in my late 20's. Mainly i'd like to make it a bit less of a fume-y(?). yeah, i know... comes with th' territory.

I totally understand... my car reeks.... haha... but I love it anyways... and love getting out to go to the girlfriends, smelling like exhaust but then the 'rents look at me funny.... oh well...

jgonzRX7

Yep, same thing here .. Guess i'm looking for a happy medium.. but if there isn't one, I'm keeping it as is.

Mazdatrix sells a high-flow cat that bolts up to the RacingBeat header. I run that cat along with an air-pump and my car does NOT smell at all. You might want to give them a call to discuss your needs.

I'd also suggest that you read this article entitled Rotary Tech: Catalytic Converters up at www.rotarynews.com Good luck!

Thanks for the tip, i didn't think they had one that would... I'll definately check it out. I hope my air pump still works, ideally, I could find a cat that doesn't need the extra 02....

thanx for the link - just when i think i know of all the '7 sites....

Huh, thats wierd I thought the mazdatrix high flow cats didnt require the air pump.

inittab

Well the one have does.

Here is the picture of it.

Hmm....

If a car smells that bad without a CAT, and Ive been driving around with a stuffed up nose for the past few weeks, I wonder how bad my car smells, with only the stock collector, and what I think is the thermal reactor left.....

jgonzRX7

dunno.. mine isn't over-the-top smelly, but after drivin' it for awhile i get out smelling like I've just finished snowblowing w/ my p.o.s snowblower!
