Furthermore, with that set-up the only way that I'm aware that one can truly rule out CEL's is to re-map the ECU. And, that comes with it's own separate cost .

Luckily I have a ROW tune on my car. My only issue that I have is purely sound. I have a deluboz v1 muffler which is nice and light but with the cat-less setup (ebay headers [which by the way seem to be built fairly well and are wrapped.]) and my own made bypass the whole thing is just too raspy and well I think too low on the back pressure. I was hoping adding an S muffler I might increase some of the back pressure and possibly gain some of the lost low end power... but idk if it works like that. I also put on a very small UDP from precision chassis works for good measure.

One day I would like to put the car on a dyno and see what kind of numbers come about.

And yes Danger, the only "fool-proof" way of doing away with the CEL is to reflash with one of the many flavors of aftermarket or RoW software out there.

Wicky Lawrie - 615-226-4928, Owner of Renntag Motorsports, Nashville, Tn [I]was able to defeat the CEL for nearly a year with the install of the headers...

I was shocked too when he said he could do it, especially after reading these forums for so long, but this guys ROCKS!

Anyone near Music City USA needing Porsche service needs to call this man! He knows his craft and is not expensive. You may have to leave it with him a week or two, but it is worth it! And cash is king...
