Hello everyone. I'm new to the site and have a few questions about some headers that I am looking at getting. I am looking at getting a set of Dynatech headers with high flow cats and mid pipes. I already have Corsa Touring exhaust and Volent air intake. I was wondering how much louder the headers would make my truck, i'm trying to keep it on the quieter side to prevent attention from the cops and keep my neighbors happy.

I was also wondering if anyone has these headers, or other long tube headers with high flow cats on a newer Silverado, and if their truck throws any codes after the upgrade.

Thanks for the info.
