Ok trucks a 5.3L avalanche. my hanger where the tips are just broke again and its the 4th time ive had to get it fixed. im kinda pissed about it so im gunna change it up. ive got true duals into flowmaster 40's. i want it to be a little louder so would just puttin turn downs make it louder? ive heard if you do have turn downs it makes it drone and resonate. any ideas?
