New to forums, need some insight

[Canadian_R32]

Hey all, new to forums and I'm seriously considering a Yaris 5door RS with "Package B" (Keyless, A/C, Power Windows) and few other goodies. First I'm going to ask for your honest opinion on the car (I'm probably going to get biased answers but hey it's a Yaris forum), second if I should get these "goodies" that I mentioned. Of course I'm looking at the Fit, but also the Rabbit as well.

The goodies I'm considering are, (prices incl installation and are in CAD)

Carbon Fiber Dash kit $379
Auto Dimming interior mirror with compass/thermometer $353
Lowering springs (TRD supplied by Eibach) $971
Borla Exhaust (I guess another TRD part supplied by Borla) $714.50
and center arm rest $102.25

chances are I won't get the springs cuz that's just ridiculous how much they are, the exhaust is what I'm really interested in.. has anyone here got the dealer installed Borla exhaust? if so how does it sound?
