This is for a 2017 Chevy Silverado 1500. Solid build good quality but not for me. Could have to do with the truck 8cyl to 4cyl engine allows exhausts to make many different tones. Not loud enough for me this is only a moderate tone and in 4cyl just a puff puff puff. The brackets we're cheap also had to buy new ones the original wouldn't tighten nuts just stripped on bolts. Would of never bought this product but Salesman said this would be a good choice for what I was looking for. Deep growl no

This is my third Gibson exhaust system I have purchased for my last three new trucks. I do not even look that other system any more because of the quality, durability and price for what you get. When I buy my next new truck it will be a Gibson exhaust for that truck too. This system also has a great deep sound for a truck, but not to loud.
