Just had a good read an look at the pics.......@wazzer system looks good and I don't mind a bit of a rip out of it as long as it not takin the p***.
Take it the issue over the rear beams to do with it being 3" as opposed to the smaller standard size pipe.....or is it heavier? Seems from comments here there may be one or two little issues fitting, but for the money I think it's gotta be worth it as your even getting the 3" down pipe!!
