Got a question about the dc2

[ekvtir90]

Thanks alot for the info now I'm thinking about what I should get a 2.5 or 2.25 inch pipe diameter, would i loose too much with 2.5?
I would call that place in ringwood but its just too far from where I live at least an hour drive. I need some where locally northern melbourne side, so if anyone knows a place they recommend that would be great.

Dougle is your brother exhaust something like this http://www.youtube.com/watch?v=dnlV_kZpIzs if it is I'd love an exhaust like that how much am I looking at for a muffer like that?

Or its probably more like this one http://www.youtube.com/watch?v=_Kew_QuGLDM it doesn't sound too loud on low range but louder on higher revs?
