I haven't done too much online shopping for parts but I'm pretty sure we're screwed when it comes to ordering from Canadian dealers. Our market size just can't compete with the market size of the Americano gringos.
Even if you found a Canadian online dealer they also have to pay the shipping, duty, and taxes to bring it across the border. They would just pass on the costs to you (and probably mark that up as well).
I would search online and then see if your local retailers can match that price and go from there.
http://www.newenough.com sells limited parts but seem to have good shipping rates. It was $60 to ship an exhaust versus about $120 from other sites. You being in Newfoundland probably doesn't help with shipping rates either (I'm just guessing).
So... Spooph, if I ask you nicely can you smuggle an exhaust pipe over the border for me? I can even suggest a body crevice that it could be smuggled in. You could pretend to be Han Solo but you'd have to walk like C-3PO. Hahaha.
Thanks guys for the info, it was helpful. I also maybe interested in a "friendly" boader smuggle...i mean exchange. I really want a yoshimura carbon fiber exhaust...but 500.00 plus is way steep. The other stuff i want i can find, but its this damn exhaust thats killing me. ANYONE KNOW A CHEAPER SITE OR HAVE A SECOND HAND ONE FOR SALE??? Thanks again guys for your help.
