Muffler model #?
 

Ladies, boys, and other cat owners.

What's the model number of the mt approved 3" Maggie (that's quieter than most)?

(FWIW, I'm not running a cat. It's been retired)

This guy?

Magnaflow 12589

The fact that you say "maggie" indicates that you should be familiar with this :)
but here you go anyway: https://www.miataturbo.net/general-m...12579-a-84584/

Vlad, stupidly enough, I couldn't think my way out of a paper bag, er, erm, figure out which model was actually the correct one.

Thank you for the linky, mang.

Vlad, sorry, I've been re-reading that thread, and am still confused.
Isn't 12578 quieter than 12589?

I'm not going to look at the specs of the mufflers. You have been told the MT spec one. If you want to know which is quieter it is the one with the larger chamber. Meaning the biggest muffler.

Thank you!
