Headers 1-7/8 or 2 inch primaries??
What are the pros and cons i amlooking for a set of long tube headers and off road catless pipes my car is a 2015 stingray with 3,000 miles and completely stock?? Am going to be adding headers cold air intake E85 all at once and in the near future a supercharger not sure which one yet but right now my concern is which headers the 1/78 or 2inch?

2 inch will make more power but you'll lose some low end torque, however, will pick up the torque on the big end. My opinion would be to do 2 inch always on any FI engine. NA should run 1 7/8.

NA stock, go with the smaller tubes as you will make power thru the powerband,not as much as long tubes at the top but the car will be making more power in the RPM range that you will be driving it in .....

done it plenty of times on a 2'' bolt on car, there is zero loss in low end tq with a good kooks or arh.
