RLS for sure is my recommendation. I have a 2016 Spyder RSS SM5 with a Baja Ron Open air element kit, E3 plugs with 10mm wires, RLS Twin Kaos pipes with Cat delete and most important a Monster Stage2 Performance map done by Wicked Performance. After installing the headers I found there was significant power and torque increase. More power per twist of the throttle. More muscle rumble from the pipes and I suspect better gas mileage. However I did not install performance parts for gas mileage.
