No Mate i took it off and put it back on once the full exhaust was fitted up. I had to remove the complete exhaust including the collector box and had to modify the rubber mounts to get it it to all match up with the headers , all together nice and tight doing it that way. Took it for a burn along the motorway and through traffic and not one pop , behaving itself very nicely

Funny thing is i was heading along the Esplanade at Burleigh and saw a very familiar Rocket parked up , was Les and the Mrs visiting family , he heard my Rocket and poked his head over the balcony hahaha, made a quick stop for a gday.
