Good place to buy exhaust?

I have pretty much settled on what I want to do with the intake and exhaust on my 2015 RGS. I will be getting a HD SE Stage 1 Air Cleaner, Vance and Hines Monster Round mufflers, V & H Fuelpak FP3 auto tuner and a Rush High Output Performance header. My goal is less heat, better sound, better performance and not too much louder. I intend to do the install myself. I am looking for advice on a good company to do business with. Looking for good price and good customer service. Is there a sponsor on the forum that offers the members a discount or someone you have had success with? Most likely, I will have to have the products shipped. Looking for your recommendations. Thanks!
