glasspacks?
so is it true that glasspacks dont last on a rotary? is there another alternative to glasspacks? anything similar to it or something that can be stuck into the pipes to quiet it down.

yah, glasspacks dont last long. If you running a midpipe (no cat) a good way to quiet it down is to run a small walker dynomax or flowmaster muffler as a midpipe. Makes a big difference, and doesnt hurt performance.

Glasspacks will melt pretty quick with the hot rx-7 exhuasts...
I was reading that the 3rd gen guys are using the borla XR-1 3" in - 3" out baffled mufflers are midpipes inplace of the cats to quiet thier straight exhuast cars down. |
Mazdatix tests said that they measured Glasspack muffler life by min. or trips around the block. I take it they were not designed for rotaries. Hell, in a Summit catalog, Flowmaster had a little notice: "not intended for rotary motors". I have had a $20 Thrush Turbo muffler on my 1st gen. for about 2 months and I can slowly hear it getting louder.

Whatever the muffler is, just make sure (ASK!) that it's packed with steel wool, not fibreglass.
|
can i stuff steel wool in the piping to quiet it down. i need something other then getting another muffler welded on again. dont got any $$$$$

My TII came with them. They seem to muffel ok, but get a bit raspy at highway speeds / 4000 rpms.
