Thats what these forums are for...one thing I would keep in mind. Be very careful with a 275 tire on a 11" wide wheel. You won't have any rim protection at all and opening yourself up to wheel damage.
A buddy of mine has a 2024 Mustang GT with the non active exhaust. He wants to go cheap and just do an S550 quad tip muffler (Borla S Type) and he has them from his previous S550 Mustang. He will either get a new quad tip rear valance or cut out the OEM single tip valance to get the quad tips...
