Hello everyone,,
I was first looking at just going to a good muffler shop https://showbox.bio/ https://tutuapp.uno/https://vidmate.vet/ and getting it straight pipe first. Then getting the cobb tune with the intake, next blow off valve for noise, and maybe a down pipe? Is this a good route, or is there something better?
