I finally got around to putting flashlegs old greddy kit on my 91 Miata that replaced my original 92 Greddy Miata I sold at the beginning of the summer. The exhaust I had on my original turbo Miata was a bit loud for my taste, 2.5" Dowpipe back(no cat) into a dynomax turbo muffler and out the back, so this time I spent some time doing to research and put together an exhaust I am extremely satisfied with. My goal was to have an exhaust that was extremely free flowing, but wasn't much if any louder than the factory system. Here is what it is: Racing Mazda 2.5" downpipe into the midpipe which is 2.5" as well, but with a glasspack style resinator installed, from there it goes into the bend and into a dynomax turbo muffler and out the back via a Silverline 3" tip. Not only do I love the look of this exhaust, but it is very quiet and free flowing. I choose not to use a cat as emissions aren't enforced where I live and my car will spend more time on the autox track than the street more than likely, okay maybe not. I haven't noticed a difference in spool from the system on my old car to this one. The glasspack style resinator toned it down a lot, but I don't think it hurt the spool up. I"ll post pics later today

did it kill the raspy-ness?

I've got a 2.5" w/ dynomax and that ****** is raspy as hell.

Acutally sounds really nice. I like it.

It did kill the "raspyness". That was what I disliked about my previous setup. With the top up it was loud, but not too bad, but with the top down it was just too much for me. I don't mind an exhaust that is a bit louder, if it has a good tone to it, but I don't like to draw attention to myself either. The guy who bought my old turbo Miata had a "fart can" style muffler put on his, with downpipe back 2.5". It looks better than I thought it would, but it is loud and resinates like crazy. He plans to put in a glasspack like I did and I'm sure his setup will be good then.

i hollowed out a 2.5" cat, drilled a bunch of holes in a 2.5" straight pipe and stuck it inside the cat, stuffed the gap between the cat body and pipe with steel wool, and then hooked up a thrush 28" 2.5" straightthrough glasspack.
quiet but deep and smooth at idle, not loud but deep and smooth when on it, but it resonates in the interior alot.

wont the steel wool burn up? I mean if it burns when I put a match to it, i cant see it holding up for long. Fiberglass would probably work betta
