look at what I made

this was a 24 inch glass pack. It sounded like broken glass so I cut it in half. The old sube needed a resonator without catalyst. All I found on the net is a glass pack looking straight through...

so I multiplied the stroke times 4, and got this roughly 10 inch resonator, out of the old glass pack. No catalyst. It is working well already...

This could easily apply to turbo subes...

this is the insides. 24 inch length couldn't even survive my 1781. this is cracked in many places. shortening the length, with carbon steel weld in the middle, it ought to hold it. It gets very very hot in the oe spot for resonators, meant to carry catalyst convertor heat.

Nifty. Yeah, isn't the shortest glasspack like 18" long? My buddy from HS did something similar on his RX7. Glasspack for the cat, glasspack for the muffler. It was awesome!

I did forget to mention the glass fiber packing has to go. nothing survives real fire, real time draft, the catalyst heat catch is a roaster on any resonator. . the thick guage of the glasspack steel, the innards and easy going geometry looking like it flows was the inspiration. I could only have purchased a stainless steel version, for more money and weaker insides.this problem arises again in the higher psi turbo subes. I mentioned it here for this reason...exhaust is a ridiculous expendible costing way too much...

For those that do not know, a reosnator is not a catalyst convertor, it ctahes after heat (very hot) and meant to aide in flow to the back end of system.This aides in exhaust getting up to temp faster, sounding larger and much much calmer at the same time. No backfires and snappy twacks in the cold, and very mellow nice when warm. The oe resonator has a great spot for after fires from catalyst, but insane for some engines to be a second catalyst. I know of many more than not that cannot have the honeycomb in thier resonator. This project has done me well. I pondered it for several years... the cost makes me feel a whole lot better, and i know what it is made out of. the weld is e71tgs, 90 something percent carbon steel wire.
