I dont know about that product but i know you can get BHP gain from exhausts of around 20+

There is now way your going to get 20hp out of an exhaust on a Boxster, maybe on other cars but not a Boxster. If there is an exhaust out there that will give me 20hp I will buy it tomorrow and sell my GHL system today

Yes you can, i have seen them.

WWW.FVD.DE offer a boxster one with 20bhp gain and many other stores.
This aint a scam. Its well known about the 20+ bhp for a mod boxster exhaust

Anyone interested in a used (5000 miles) GHL system sounds great but it will not give you 20hp. This is the system with the twin 5" cans

But not the zero. Show us some legit dyno scans from a reputable and neutral shop. You will sell many if this is the case. We have all heard and read from many tuners the world over that the oem system is hard to beat. Ruf says 2-3 h.p. with their system. Something seems fishy here. It's hard enough to get 20hp from intake exhaust and ecu (especially without headers and cats).
Show us the proof, we will be happy to review it!
