Any advice, megaphones Options

[vintage914racer]

So I have a set of megaphones for my 914-6 racecar and am wondering what to expect if I put them on. I know it will increase my low end torque a little and increase my high end, or thats at least what i have been told. Anyway, I am wondering if it is worth the time and money to put them back on and have my carbs rejetted for an upcoming race in September at Road America. Any advice or experience would be appreciated.

I purchased my megaphones from GPR and I believe they were built by George at European for them. Unfortunately they didn't sell a hanger and after several attempts to reach George I still do not have a hanger. Is there anywhere else I could look or has anyone built there own?

A lot of tracks have a sound limit these days, and most of them have a sound level meter and check you in tech. Some clubs have a blanket limit regardless of the track, which they test for.

Laguna Seca is an extreme case due to its now being located within earshot of a number of high-priced houses (the track was there first, but that doesn't seem to matter). They have a meter running all the time at the edge of the track in a high load, uphill section (between Five and Six), where the car is likely to be at its loudest. At most events there, the limit is so low that even a pissed off small town cop wouldn't pull you over if you made that much noise.
