Any REAL gains to mod exhaust on a 2.7??

"I also have a 2.7 engine and recently called a local independent shop to find out what can be done to give my stock engine a bit more power. I had asked about the ECU reflash with softtronics and they had mentioned it would be a waste of money on the 2.7. Stating that the 2.7 spec had maximize most of it's potential direct from the factory. And that they could do the reflash but it wouldn't make much of a change. Anyone who winded up doing it on a 2.7 chime in on this?"

I got 16 hp or so on the dyno with just the Autothority 2.7 chip for the 2000 boxster. But also got quite a bit of more low end torque and drivibility, check out my link below for a couple of dynos (with exhaust and intake).

I thought I would add, that most of the tuning of my 2.7L 2000 Boxster is based on TTP parts Link to TTP. My intake and headers are TTP and the Autothority chip I am using is based on the TTP ECU parameters. I find it interesting that TTP says that adding their chip, headers, intake and high flow muffler gives a 2.7L 2000 Boxster about 25hp, which is almost exactly what I see on the dyno. Like others have said, getting much of a HP increase out of our cars with bolt-on's and such is difficult and expensive.

Can you estimate the price of the chipping only. That seems like the biggest bang for the buck.

"Can you estimate the price of the chipping only. That seems like the biggest bang for the buck."

There are several folks making good-performing chips, the only one I have experience with is Autothority's chip which is very expensive these days. It has increased in price since I got mine almost 2 years ago. The current price is just under 2K Autothority Website.

As others have wisely said to neophytes like me when I first got my car, modding our cars is a slippery slope of expenses, its easy to get carried away, I know I did. Even so, it sure has been a lot of fun and interesting for me to learn about and mod my 2000 Boxster, my very first Porsche. I was driving today with a big grin on my face and continue to wonder at the performance of this "base" model Boxster (104 mph in third gear, sure got there fast, must be the cold weather....).
