Installed dual Borla system by myself lying on my back under my 2016 TRD 4x4 Tundra. Muffler was a little heavy and awkward but I got it on. Cut stock system off w/ do-all saw. Everything lined up and was easy to assemble. Looks great! Not too loud but sounds good. This is my 2nd Borla system. 1st system, installed on 07 Tundra that I sold, still looked like new and sounded good after 9 years of rumble.
The exhaust is pretty quiet. I was dissapointed at first. But now I can appreciate the really low rumble at start up and cruising. It does not get louder when you accelerate. It does not have any drone. If you are 20, this exhaust is not for you. The chrome tip looks really sharp. I wouldn't expect big gains from this exhaust. I do like it though.
