My car has the K-27 Turbo. I had the "1 Bar" spring, but threw the stock (.8 bar) spring back on for engine longevity (the car is plenty fast anyway).

A couple years ago I pulled the CAT and stock muffler off and replaced them with a dual-out 3" diameter Fabspeed exhaust. My engine oil temps went down (less restrictive) and the power (and noise) went up. I guess in this config it is "track only" as far as the state is concerned.

When I choose to make it "street legal" I pull the Fabspeed exhaust and bolt on the CAT and OEM muffler (it doesn't take that long, really). It passes smog easily like that.

Most smog techs aren't used to looking at a flat-6 shoehorned into a rear-engine Porsche. Their confusion works to my benefit. I've never had an issue with the "visual" inspection.
