Barry, Dirk,

Whats the recommend tailpipe diameter for the Kingtech 180G? My inside diameter is 3 inches on the Viper Jet.

Also how far are you putting the tailpipe of the motor into the SS exhaust pipe?

Thanks in advance!

Craig

Hi Craig, the recommended distance between the tail cone and pipe is all in the manual, which is about 20 to 30mm, as with the diameter, it has everything to do with the length and its taper, please contact the maker of the pipe for its rated thrust. Otherwise, if you need a replacement pipe made, please contact Tam at tamjets.com

Thanks,
Barry
