you might find they won't post large items internationally. I tried to get tyres from them and they said item to large to ship. Might be differant to Aus.

From their website info on international orders

"RevZilla Motorsports will accept international orders totaling $300 or more.
Orders will be shipped by USPS Express Mail International.
Tires, hazardous, and oversize items (like large luggage or exhausts) cannot be shipped internationally."

You would probably find they would ship end cans but not full systems.
At present prices though, Morepower Racing and Parts Giant are cheaper.
