Default Exhaust ideas on high HP setup

looking into a few exhaust options.

i have a 3 inch short downpipe that comes off my PT67

1st full custom exhaust (LOUD)
2nd use my exhisting invidia 3inch with some kind of cutout
3rd use my exhusting invidia with an external wastegate to act as cutout


any ideas? Thanks.

I'm going the cutout route since the local pd did not like my last "loud" exhaust.

Get a cut out or an APS 3.5" TBE.

aps 3.5" for the win. who wants to get ready to drive fast whn you could always have the power ready. cutouts are coll but a ghetto fix... if you get a cut out you must make a muffler out of a folgers can... complete the look. lol

my downpipe is pretty short though it is 3 inch. there is not much room what so ever to run a bigger one. I will need to have a mid pipe fabricated. is the 3inch downpipe choking exhaust flow?
