Hello all! i have a 1991 F250 with the 7.3 IDI N/A. As of right now, it has 2.5 inch true duals with glasspacks. Well the packing in the glasspacks have burnt out, so now it sounds like it has fart cans on it . what muffler would you recommend that i install? I've had my share of being obnoxiously loud, now I just want it to sound good! thank you all!!

 

flowmaster Super44 try them.

 

4 in y to 4 in straight back one elbow at rear of cab to a 36 in x 10 in "Pypes" stack sounds awesome and it breathes better too
