Clifford Headers and flowmaster u fit

Any muffler review within 1 month of install isn't quite accurate IMO. Mufflers take time to 'break in'. Even my Thrush welded (Dronemaster copy) didn't sound the same 2 weeks after install. A fiberglass packed one will take a LONG time. The turbo muffs on my truck took 6 MONTHS! And I probably drove it ~10,000 miles during that time. I love how people install glasspacks and immediately afterwords say 'It sounds stock, anyone that says they cackle is wrong'.

Just something to think about.
