Took me around 5 hours all up...but that's because I didn't have all the tools and I cut/measured/re-cut my perforated steel tube from a 1 meter tube. Ended up costing me around the same as if I just bought the race baffle kits on eBay 'cept those are already cut to size and angle. If you get the precut kits, removing stock exhausts should take about 10mins (seriously easy!!!) and u'd probably spend an hour or two drilling out the rivets and spot welds, then it's smooth sailing from there.
Apparently the 05's uses a 2" perforated tube, and the 07's use a 2.5"... That's the only difference between the year models.
Oh another advice, get some washers with 5mm internal hole diameter. The factory baffles are what the stock rivets rivet to, you'll be removing those and the holes on the titanium skin are way too big to rivet again, that's when you'll need the washers, glue it to the inside of the titanium shell and rivet against the washers instead. The black cone also has a 5mm diameter hole so the washers will be a perfect fit. That's what took me a while because I can't find the right washers so I had to use 3/16" washers and drill it out with a 5mm drill bit. Warped around 20 washers before I finally got my 8 good ones.
