Group Buy - H&S Bypass - 997.2 - June 2016
- Thread starter Giff
- Start date
I don't know the Cybox pipes, but I do know the H&S pipes and had them fitted by H&S themselves couple of months ago, proper exhaust specialists who know a thing or two about Porsche systems.
The pipes are rock solid in terms of fit and finish and have made the car sound more aggressive but no less of a high quality machine. H&S used their first customer's 997.2 to get the patterns/jigs sorted so they fit properly, the pipes are BS304 16swg, tig welded, mandrel bent, with 10mm thick flanges and 1.6mm wall thickness (prevents too much sound resonating through the wall of the pipes). Information that may be useful for comparison.

Mine went on today.
Sounds bloody marvellous, especially with PSE. Not at all antisocial and you can really tell the difference now with the pse button pressed.
Wish i had done it 2 years ago really, sounds like its supposed to especially as you pass 4k rpm. Fuel economy will suffer as you wont want to change up
