If you worried about longevity I would just get basic mods done like Intake, Exhaust, and running a mild tune that only increases boost by a few PSI like JB+.
downpipes arent bad for cars longetivity are they?
Yes I ve been searching and I found that AR designs catless are the most popular. Ive also heard making them "catless" gives you error codes sometimes. Is this true? Do I need to do anything about it?
Thanks for the help
