    Just what i was looking for

    One of the best exhaust i've used. Not to loud or to quiet just fine. Noticed a few gains not to much but noticable. Great cold start. Just wating on a CAI to pair it with and can't wait to hear the roar a bit louder.

    Amazing sound

    I have had many Silverados with different exhaust systems, and most Silverados have a similar sound even with different brands. But, this exhaust makes your Silverado unique sounds nothing like other exhaust systems. Highly recommend. Cold air intake is definitely next.
