If I replace the stock Exhaust on my 2015 VW GTI with an aftermarket cat-back will it mess up any sensors, or cause problems with Inspection & Emissions, or Warranty from Dealership?
***Please note I will be moving to California in a few months...and I hear
California is crazy with emissions stuff.
It will do all of the above !
It shouldn't mess up sensors because it is a Cat-Back...meaning it comes after the CAT. I am keeping stock downpipes, and CAT. What do other people think?
The sensors should be fine, but not sure you will pass emissions in California...
warranty may be voided but all else should be ok
