Borla Exhaust Systems Reviews

One NASTY exhaust!

Reviewed By Matthew W (Whitestown, IN) Reviewed for a 2015 GMC Sierra —10/11/2017 5:56 PM

It didn't take me very long to decide on the Borla ATAK system for my truck once I saw some of the youtube videos. This exhaust sounds wicked. The cold start in the morning will rouse the neighbors if they are light sleepers! It really does calm down once the engine is warm though. It is surprisingly quiet while cruising at 70 but she really rips if you put your foot in it. One of the tips was wielded on crooked but Borla customer service is sending me out new parts.
