I've been searching for the last half hour and I can't find anywhere that sells a cat-back exhaust system (or any exhaust system for that matter) for my 1985 n/a 13B.

Racing Beat I've heard is good, but I haven't been able to find it for an '85.

 

search their website..their cat back is simply a muffler. the main converter has a pipe rearward of it (called the extension pipe) that connects to the muffler. racing beat is top notch and comes highly reccomended. for the most power gain on a stock port and with minor mods, the dual pipe system is the best.

 

As mazdaverx stated there are no "Cat back" systems for our cars, just a replacement muffler that is free flowing.

 

Interesting. I found the REV25 muffler and the pre-silencer units. weird how they do it that way.

Thanks for the help!

 

But you can always get something custom fabbed up. I'll post up a photo later of my magnaflow muffler and dual magnaflow tips.

 

Here's the catback portion I had fabricated a month back or so

 

They have it... it's hard to find. Their exhaust section is confusing. Some items are in racing, some are in exhaust components, some are in exhaust systems. Total PITA.
