I'm looking to install either a test pipe (ebay) or free-flowing cat on my 95, but just can't decide which is better, or if I should install one at all. I live in Florida so I don't need to worry about smog checks. Any opinions?[/img]

It depends on your catback system. I had a catpipe on my '91; combined with a Mongoose system and Tanabe header, it sounded great

I know on other systems, it might not be as nice though. I never suffered a dirty bumper with this setup.

The stock factory cat was already a free flow design; the aftermarket ones do little to improve on this, though they are undoubtedly better than a generic can with flanges welded on. After 60k mls, the stock cat starts to deteriotate.

Use a cat unless your running FI. The sound will be annoying and your most likely going to lose torque with a test pipe.

When I had a turbo on my 1.6L, I ran a test pipe and loved the added power and sound.

I think my cat may have already failed, 'cause I have a nice bumper stain if I don't wash my car weekly. It's been raining ALOT in southwest Florida and my only chance to wash is on the weekends. She's my daily driver, and it sucks not to keep her clean, if you know what I mean. But, I will continue building a great Miata that I will NEVER sell, and this is just one little step in the ongoing process that I plan to share with everybody on CR.net . Thanks for all your help!

the exhaust was kinda stinky for a while (rotten egg-ish) but went away after a month or so ... sounded more throaty w/o the cat too, although I also went to a Mazdaspeed exhaust as well.
