so i have true duals with glasspacks from my front two cats on my 2000 f150 5.4. and i have no sound coming from my right pipe! i mean there's some tone but the cracking noise only comes out of my left pipe. everything is welded and done correctly and im very confused....at first i thought something was wrong with my engine but i don know if thats the case. it just sounds like air coming out of the tip. idk maybe something wrong with the glasspack??? any ideas would be greatly appreciated
