The stock 5sfe exhaust is horribly restrictive and even a stock motor will respond well to especially a header back exhaust. The $$ per HP argument is subjective and based entirely on the builder's goals and expectations. A 3" exhaust is maybe not the ideal size for a stock 5sfe but even that can result in an overall improvement over the stock exhaust and the most available exhausts just happen to BE 3". I was skeptical myself until I helped install one and had a chance to see the results.

I was having a rough day at the office yesterday. I don't get grumpy around here very often but it does happen. Sorry about that.
Sometimes I have to remind myself that "general rules of thumb" don't apply to all cars. More so with the MR2. That's why I referred the OP to mrturrari's post.
If there's one thing about me, I am man enough to admit when I am wrong and in this particular case, I was.
