Pre-cat bypass vs. secondary cat bypass

[sparker]

Hi Guys,

curious to know where you picked up the sport cats from? Any links?

I recently replaced my Australian stock headers with some Top Speed units. Our stock headers look like they would be a neat upgrade for you American based boxsters. PM me if your intersted in buying them.

This is the company I got mine from but the picture on their site is of a different application. They actually look like the Fabspeed pic.
