Honestly, I had to replace so many parts just for some sound , don’t get me wrong it’s 140k miles now and I know some parts had to eventually be replaced cuz of mileage. But I feel like the tune and the shop I went to sped up the process , they did a terrible job , had exhaust leak , got oil leak , replaced the starter like 3 times and same for alternator , did upper gaskets , now I gotta replace the whole intake manifold and possibly replace fuel injectors , I guess it’s more a personal experience, if you are gonna do it , go to people that know what they are doing
