The difference between the standard exhaust and a full 3" system is quite amazing.
3 inch front pipe - www.flyn.com.au
~$450 AUD
pipe/flange ID = 74mm
it comes with these gastkets, fitted fine
I dampened the wrap with water then wrapped it on using two hose clamps and the two wire clamps supplied with the wrap.
It took ages to dry in the sun so I sped things up by sticking a heat gun in the pipe!! I've never had a whole lot of patience
I then masked off the flanges etc ready for painting
the paint I used, flame proof and apparently able to withstand 1500 degrees farenheit!!
the finnished painted pipe - ready to install
