have you done anything with the exhaust on the yaris?

I saw your other thread and wondered that there too but didn't post.

I know you have done the header but what about the rest of it?

I am very happy with the gains I have gotten on mine and all I have done (for power) is the intake, header, exhaust (not axle back), and light weight pulley.

I have done other things like springs, sway bar, short shifter (x2), and so on.

you may want to consider the exhaust as it seemed to help a lot for me. Malibuguy made mine and it is mandrel bent 2" with a glass packed muffler. I painted it with barbecue paint (black) so as not to be too showey.

Love the Si. I think 2004 was the last year of the hatchback Si. Great looking cars all around.
