Picking up my 2017 Magnetic ST with Smokestorm Recaros and ebony wheels from West Virginia next week and driving 560 miles back to New York. Can't wait to hit the backroads. I plan to install a turbosmart BOV in the first week and once the engine break in is complete i will cut the resonator out and go stage 1 with crackles from stratified. I want to get a downpipe with this but i am torn as far as going hi flow or catless. I would love to hear the turbo spool thru the exhaust and i'm sure the crackles will be louder but i don't want to have to swap back to stock dp every year for emissions. How much power difference is there between hiflow and catless and is there any way to set monitors as READY without a cat?
