I have a 2015 3.8 R-Spec Coupe. I am looking to put a turbo in it shortly but would like to do some other work first (ie Clutch, Flywheel, headers, Exhaust, etc...). What are some good recommended parts for these upgrades that will make my transition to a turbo a little easier (cost less). Im pretty set on the Borla Exhaust, but I'm open to suggestions for other parts. Thanks in advance for any assistance.
