Headers ?

[skippy911]

Wondering if anyone has done a Header swap on their IS ?

I was thinking of swaping out my stock headers for something a little less restrictive.

It looks relatively easy, but are there other mods I'd have to do ? O2 sensor ?

I've heard that the power gains are better than a cat-back exhaust.

Thanks

If you get the Toyomoto header, their O2 sim works. Best bet is to also install the low restriction Y pipe with the header. It's somewhat difficult to remove the stock manifold, but with two people working it's not that bad.
