Will, thanks for your reply.
I did reach out Weston and they sent me a ballpark estimate of around 150 gr weight for the .60 to .80 genesis aero pipe, and a length of aprox 400 mm.
It seems to be a little on the high weight end compared with the Hatori # 606 (114 gr) and Macs 10 cc Quiet Pipe (128 gr.) but I think it's worth a try and also given there are not really much options today other than the NR 50400 pipe for 10 cc glow engines.
Does anyone know/recommend of any carbon pipes being offered on the market, Salisbury pipes still offering carbon 10 cc aero pipes?
Regards
JP
