991 GT3 centre bypass

[Adrian-9iafn]

Hi all,

Does anyone know if something like the shark works or JCR centre bypass/system cause issues with warranty or benefit from remapping and cause warranty issues

On a 991.1 GT3 I want to be careful but dislike the way the flap opens at 4k using the exhaust in sport. Much prefer to possibly leave sport off and fit a bypass ?

Thanks, I’ll keep it stock then !

I wonder if there is any way round the annoying boom at 4K when you accelerate. Usually when you using reasonable throttle and short shifting, it sounds crap, like something went wrong and you lifted off

I do try to but my journey starts in the centre of town, I’m disappointed if I can’t hit 9k with WOT at least once a trip !

I haven't seen the new centre bypass in Ti, any links, I didnt see it on their web site

Yes I agree with this and have seen the obsessed garage video. I have not tried it for myself (keeping the valves open) but suspect the boom in all configurations would be annoying.

I would like to see how it sounds PSE off with a bypass ?
