hey don, how much do your pipes go for? just wondering. my measurements are as follows, 85mm inner at turbine, 90mm outer at turbine, 80 inner at tail, 85mm outer at tail. Gosh the length i cant recall but i would say its right about 20 inches. let me know. i know how well tams pipes are, but wow, i cant imagine shelling out 170 for it. i am active duty air force and in maintenance, i have the guys out here at the sheet metal shop that will roll and weld it for free, well maybe a case of beer. thats how i got this pipe made, i just told them the measurements. thanks guys
