Check out the "Muffler Bypass Pipes" and watch the video.

Make the PSE sound a bit lame !!! Ok, I know nowt about cars but for $300 thats cheap for a good noise ! :D
So did they take off the silencer boxes or something ?

I've got a set of these for my GT3 but ain't fitted them yet. Intend to do so soon and try and record a before / after. Power gains are dubious and they are a pain to fit / remove as you have to remove the silencers.

Plus points though - less weight @ rear of car and a seriously raucous soundtrack - looking forward to the GT3 Cup soundtrack!

Do invalidate the Porsche warranty ?

Probably so for the records and in case anyone views this my car has never / will never wear these ;)

I'll let you know how a 'friend' with a mk1 GT3 gets on with them when i give them to him...

only if the exhaust is a consquence.... PGB have confirmed that mod's dont invalidate the whoel warranty as long as they dont cause a failure

and a more free flowing exhaust must be better !

Surely these cannot be legal in the UK?

Got a funny feeling that I would get lots of complaints from the neighbours when I start up at 6:00am if I had a set of them!

Sometimes its good to give the neighbours a rude awakening :wink:

Probably still quieter than the modified Corsa's prevalent in town cruises.

I wonder of any makes (aside from Porsche) something that you can turn down the exhaust noise, like a butterfly valve.

I’d love a loud setup but then you cant sneak out at night or go on tracks.

I wouldn’t even care if the switch was manual under the car jobby

The DB9 has an automatic bypass valve - not quite sure how it's triggered, but I think it's related to engine revs and accelerator pedal travel?

As has the AMv8 - but the dealers tend to keep them locked open so the test cars sound awesome!
