Well, I'm not sure if I'm the first one in Australia with the HOGZAUST mod (just a few too many posts to read through to find that out)!, but all the power to you Hogmeat!!
Here I was looking at an expensive exhaust upgrade to get that Boxer rumble happening but let me tell you I am happy with my Hogzaust stage 2 (sounds so rice just writing that haha).
Anyway, I thought this whole thing was a piss take, but having first hand experience, I think Hogzaust is going to take over the world!!!!
Good work mate.
