Amazing piece to add to your truck. Works just as advertised. Im a welder by trade and must commend the craftsmanship on this muffler. Its is top quality! I love the sound of my 5” straight pipe, but with the turn of the switch I can tame it down to the sound of a stock pickup! Highly recommend!! Install was a breeze for a DIY garage mechanic like me!

*owned & installed for roughly a month* This is absolutely amazing! I love the ability to go from stock sound to straight pipe! While installing it (i did it myself) i had a couple hiccups (self induced). The people at GDSS are amazing and quick on responding to help. Your getting what you pay for and its quality!
