Ok,=20 Rusty,  I give up.  What won't I stuff in my tail = pipe? =20 Money?  Nope, already done that! Several times {:>).  So = far, I=20 have found that the following materials have not worked:
 
1.  Stainless Steel scrub pads = ( a dozen or=20 more stuffed in each pipe).  Lasted longer than anything else = I've tried=20 (also the cheapest material purchased)
 
2.  Metal exhaust resitrictors = (three=20 perforated mild steel metal disk around a 1/2" pipe).  Effective = in=20 reducing the volume of noise, but lived less than 2 months.  This = might=20 have some promiss if made out of heavy gauge Stainless = Steel.
 
3.  SilcoSoft a scila based = material rated=20 to 2000F.  Withstood the heat just fine, but the exhaust pulse = blew it=20 into dust in one flight.
 
Some suggested = materials
 
1.  Stainless steel shavings = (metal working=20 residue)
 
2.  Carbon Fiber (my guess is = that it would=20 withstand the heat but would succum to the exhaust pulse = blast)
 
3.  Rock Wool =  material/Lava=20 rock?  Don't have a clue but sounds heavy.
 
 
By the way, Rusty if you have 3/4" = of good=20 threads, then you really don't need to expoy the fitting in.  A = large=20 soft aluminum washer has sealed my AN16 adapter into the pump inlet = just=20 fine.
