Just went to Budget Performance (
http://www.budgetexhaust.com) and talked to the owner Jeff. Had a chat with him about the possibility of making headers/y-pipe for the Camrys.
He said that if he's going to make the y-pipe it'll cost around $250+/- CDN each (without cat) which is roughly $160USD.
As for the headers he said the shop is quite busy in the coming weeks but if he has the time (and perhaps someone can donate the manifolds) he'll definitely give it a try.
Just passing the words to those who are interested.
I also told him about this site so he'll probably be checking it out.
