Light(er) weight muffler for autocross

I have a base Boxster and am looking reduce muffler weight from stock. The car is autocrossed frequently but also enjoyed as my wife's occasional cruiser. For that reason I don't want an overly aggressive tone and would like as little drone as possible.

My priority order is:
1. Weight reduction from stock;
2. Price;
3. Performance; and lastly
4. sound.

Any input would be appreciated.

I am looking to run this muffler:


If you have the funds for a titatnium muffler, there are some very cool options out there... as for drone that is going to be a trial and error... I have flowmaster hushpowers now and while they meet before the exit I still need to tune with hemholtz J pipes. I have a good drone at the 2600 mark which is typical for dual can set up.

Someone here used it for a v8 transplant. By my measurements it’s a bit of a tight fit. I ended up using the big magnaflow crossflow and have come to terms with the drone by driving around it.
