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]
The test pipe will be cool for a couple weeks then the sound will anoy you to the point where your gonna buy a high flow cat anyways, so delay your purchase an extra week, save up 50 more bones, and buy a GOOD high flow cat.
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.
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!
