i have them , he has a few X7 engines but i have the majority of them i believe

i used the 9901ss/41021 setup on buggy and the 2096ss/41021 setup on truck

i am thinking the 2096ss/41021 works very well in buggy as well as truck , the 2096ss is weird how much mileage it gets at the low temps it runs i dont care ,it works!!!

dont have too many 2096ss pipesets so if someone wants one they better get one quick , i better check what i have sold , i might not have any that arent spoken for
