It was explained to me that changing the parameters in the ECU will cause parts of the engine to run hotter and or cooler than other and could ultimately damage the engine and Porsche will not be held responsable for a car they engineered that has been changed by someone that does not have all the design information about the car. Porsche has the ECU designed to handle many many issues you can run into driving on the street. I was also told that flashing and or replacing the ECU will void the entire cars warranty because the ECU controls many things on the car besides the timing and air fuel ratio.

Just my personal preference. The Tubi is; however, quite a bit lighter than the PSE and a work of art. But it aint cheap either.

Porsche mailed out winter savings coupons earlier this year (perhaps to PCA members?). It was 20% off. I used that coupon to purchase the X51 headers and PSE exhaust through Suncoast Porsche in Florida. With the coupon my PSE exhaust was $1,890.

Unfortunately, I think that winter program ended on 3/31. My suggestion is to call around. Suncoast in Florida, Sunset in OR and Boardwalk in Texas are usually very aggressively priced (at least compared to what my local dealers charge). And as a benefit to me (I live in S. CA with an 8.75% tax rate) there's no sales tax in Florida or Oregan so while I had to pay $80 to have my exhaust and headers shipped and wait a week... it's a lot cheaper than the tax I would have paid (even if I could find the same prices in CA... which I couldn't).

I know all of those folks, so will do some shopping around but I don't think I can get close to what you paid.

BTW, where did you install and for how much?

I'm having a local Porsche specialist (Hergesheimer) do the install along with my 2 year service/brake flush.

My install is not a good proxy; however, as I'm using a coupon, PCA discount and my install is a bit custom (I'm not hooking the PSE into the DME, instead going right through the Carnewal solution). It's a lot, lot cheaper to do it that way and it obfuscates the need to use the sport button to get the "loud" setting and eliminates the set speed tone change.

One could also do the ashtray switch.
