Thinking about doing the $4.5K package that includes the headers, cats and exhaust system. I had just the exhaust system on my 987 and liked the sound very much, other than the system droned pretty badly between 2700-2900 rpm. Curious to see if anyone out there has done the complete system on a 981?

The 981 really wakes up with our full exhaust package. Even without an ECU tune, we are seeing gains of over 30 ft. lbs of torque in the mid range! That is huge on a non-turbo car. Peak torque is up 25 ft. lbs to the wheels over stock, and peak horsepower is up 11 to the wheels over stock. In the mid range, there are gains in the 30 rwhp range, with solid gains of 20+ ft. lbs of torque for a large chunk of the powerband.
We've fixed the droning that some were hearing on the 987/987.2 btw.

Thanks Chris. Have you guys tested the full system on a base car (versus the S)? If so how do the gains compare?

Chris@Fabspeed

We have not had a base 981 to test on the dyno, but I would safely estimate that whatever the % difference in power there is between an S and a non-S, that will be the same percentage difference in power gained with the Fabspeed full exhaust.

For example there is approx. a 16% difference in power between the 265hp base boxster, and the 315hp S. The gains I would expect would be 16% less than on the dyno chart above.
