Yes been buying from them back when they had 118 in stock, down to 9 now, I went ahead and bought two more, one for a Norvel .074
I use thick walled silicon tube requires no zip ties ok if retained well at the stinger. For sure want to cut at the bend to max out the length
for the coupler to have enough grab onto.
You can obtain Profi pipes from the Russian guy out of CA - $97.95 a pop / 11.2g
Nice and low weight 2nd level "design" compared to the older G&Z / CS pipes,
The pipe volume work well with .05 to SH .07 car engines.
