Hi,
Some advice/comments would be much appreciated regarding the Shark Werks muffler bypass. I have a 997GTS which is just out of its extended warranty and am considering this mod. Car sounds good with the valves open but I think it needs a little bit more ‘beef’ without being embarrassingly loud.

My questions are:

1. What kid of impact does it have on insurance and are there insurance companies that are recommended?
2. Does it have a negative impact on the MOT test?
3. I am based the midlands- can someone recommend an installer?
4. What has been the experience of those who have had the installation?

Thank you for any input
