How much difference is there between the 250 and 150 barrels as I fancy trying a different set of pipes from my current Tyga but if its a case of getting exhaust flanges made it may not be worth the hassle just to have something different. I do not have a large garage or machine shop at hand to manufacture items!

Also do the flanges supplied for the 300 kit fit if I were to install the Tyga pipes on a 250?
