          Great Exhaust

          Loving this exhaust, had it on almost 5 months now. I listened to sooo many youtube videos and truly thought this one sounded the best on a v6 Only issues were with the pypes exhaust hanger kit. The vibrations had one of my tips hang out the exhaust hanger a few times... until I got it welded into place. Would recommend to anyone with a v6.
