Just ordered a set of Kooks headers and cats from RDP Store and DynoSteve for my 2017 Camaro SS.
Has to be the best price by far for these parts. RDP Store has a coupon code that will take 12% off of Kooks.
Should receive the parts by the weekend so I can install and have my tune adjusted by my tuner next week.
EDIT: Received the headers and cats kit the day after I ordered which is awesome.
Did I need to spend money on a set of header for my car right now? No, but the final cost from RDP Store with their current coupon code was too good to not jump on it.
