Heat shields are just a protective barrier fm exhaust pipe - getting the CAT out is you bigger heat generator. Black exhaust last the same as chrome (ceramic coated, or HT paint) with proper care. Been running black Bub-7's for almost a year & still look new...another good thing w/black - no bluing...
How exactly does the Fullsac thing work? Order them up and then swap once they arrive or do you send yours in and they do it to the original pipes? I have an '11 and it's too hot as well. I have only put the stage 1 breather on? What is the full stage 1 mod?
Here's another way to reduce heat for not a lot of money. I put them on my RG and it's a serious improvement. 105 in the shade in Cowtown.
