Had to install new stainless header pipes on my apex but installed stock gaskets and will be ordering new copper gaskets and was woundering how well the copper ones are holding up? as well as how are the stainless pipes doing also? I know some guys have put some time and miles on them by now.....Thanks.

3500 Km's so far so good stainless OEM pipes and copper donuts no leaks no backfires and stalls fast when plugging exhaust test is done. I am very happy.
 
where do you find copper donuts? The originals are shot in my 03 rx1. Was thinking about going back to stock since I got 4500 miles out of them but if copper ones are holding up better I would like to get something a little better.
 
Copper Donuts are $17 here: http://sledtoyz.com/component/virtuemar ... duct_id=96
They are in Canada but I bought from them and the shipping was not expensive even though I am in the USA.
