Ok, sounds good. How about the CEL? Maxspeed claims their headers with cats don't cause CEL's, is this still an issue?

Yes, I still have the CEL. it appeared after about 100 miles. I'm not to worried about it right now, as I am about to do the ECU upgrade. If its still there after, I will get rid of it. Also the following is from MAXSPEEDS's website. They don't guarantee no CEL on all models. Check it out:

MAXSPEED

"All of our exhausts are made with Tri-Metal 200 Cells Catalytic Converters, obviously these are much less restrictive and flow more exhaust than the factory 600 or 800 Cells Catalytic Converters used by Porsche at the factory."

"After selling many of our exhaust parts that use 200 Cells Sports Cats we have noticed that on Porsche 986 All Models starting in 2003 the ECU's are much more sensitive we have been getting reports from customers who have experienced the Check Engine Light again starting year 2003, we have never seen it on Pre-2003 models but it could happen as well. Some who own 2003 Up models do not experience the Check Engine Light."

You know....at the end of the day, it is still $850 - $900 bucks. I want an exhaust that is sub $500, that sounds good, looks good, weighs less, and (maybe) gives a bit of a performance increase. Besides making your own, using (for instance) a couple of Magnaflows, what are our options?

rob-

the pedro exhaust will give you better sound, no power, and it's under $500.

but if you can find a good exhaust for $500 or less that can do all that stuff you list - let me know, I"ll buy one too!!!
