i apologize if i have missed a similar thread. i am currently running the standard baffle and i like the sound and the performance is ok. my problem is the packing self destructs after only a few hundred miles. i read on another site that you can replace the fiberglass packing with stove rope [available at any place that sells fireplace and stove acc.] it will not burn out and outlasts the fiberglass. will it affect the performance of the pipe, as the wrapped portion of the baffle will not be porous as with the original fiberglass? maybe its true-if its too loud, you'r too old.
