I sure have put a lot of miles on the car since.
I haven't got any more exhaust mods
But the muffler has been great. Remember to sponge it when you're washing the car to keep it nice & shiny
I don't know if i've felt a difference, but the sound is essentially the same to me. It might've quietened down a bit, but it's still a lovely sound. You'll enjoy it, i promise!
