I’m sure the owners on here but buddy if mine Jay did a nice video
Yes, I thought it sounded much better once the y pipe went on…mine is a Russ fellows non res? I also waited until after optimising and then had remap, injectors and sd sensor fitted, so it’s 660bhp and 625lbs/ft torque. As I’ve said…very happy with where it’s at, but if it was one of the last ones then I’d keep it stock bar fitting the y pipe😎👍🏻Are you saying the Y pipe did make a massive difference Macca, or asking for advice on whether it did? I have no first-hand experience of this so thought I would try it as it's no biggie to change back to standard.
