The Perfect Exhaust For Me

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

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.
