Topgear 911 997.2 Silencer Bypass Group Buy

Have had confirmation from my fabricator out at SEMA that this will fit to PSE.

Great to hear. My order has been placed. Early Christmas present...

Thanks!

Afternoon all :thumbs:,

Product- Link

One quick clarifying question. The product description says...

The X-Pipe design of the silencer bypass optimizes flows and boosts power gains as well as providing a higher pitched racing sound. This lightweight silencer bypass saves weight on your vehicle as well as increasing the power delivery.

Now it's not the reason I'm buying, but I'm curious as to the data backing the claimed increase in power (e.g. before/after dyno charts)? And how much of a bump you saw?

Thanks.

Karl.
 
Hi Topgear, can you check your PM please? My quote came to 400 quid instead of a lower one of 360-ish.
 
Silencers and x pipe arrived today, many thanks for the quick service :thumb:
 
As did mine here in California...

I installed it Saturday myself without a hitch. And if I can do it, believe me anyone can :)

And then just for yucks, I captured some clips comparing the in-cabin sound of the Billy Boat vs. TopGear pipes...

However, that (iPhone 6) video struggles to capture the in-person reality of what they sound like.

Hi Alex,

Looks a good deal can i get a code to order one please.

thanks

Fitted the bypass and silencers today.

I've struggled to find a vacuum other than the hard pipe which goes to the brake servo which i'd rather not use.

Does anyone know where I can take a vacuum from on a 997.2 3.6 for the valves?

Hi all

My car already has a gundo hack. How much further improvement would there be to the sound if I install this silencer bypass to the car?



Cheers[/quot

Has anyone in this group done a Gundo and installed silencer bypass after?

Keen to hear feedback before I pull the trigger

Cheers
