I got invited to test/hear the brand new exhaust getting installed next week by Sportec ona 997tt. They told me it sounds killer !

Not sure if its the new one they are using for the SPR1.

About 2mm ( 0.1 inches) bigger pipes diameter, approx + 5-8 hp, but haven't been on the dyno yet.

So If possible, i'll post some pics or a vid.

 

Excellent to hear. Try to get a sound clip up if you can.
