Exhaust.
If drone is bothering you, have a helmholtz resonator made. Otherwise known as "J pipe" with end capped.
http://mkiv.supras.org.nz/articles/exhaust_drone.h... Doesn't effect flow at all, this is the guy who wrote said article. http://www.supraforums.com/forum/showthread.php?69...
If you want it quietened, route those screamer pipes into the exhaust, and then silence it. Trying to remember what the name of the company that Supra owners use but they do 4" exhausts straight off the shopfront. (edit: Burns Stainless) You just need a very big resonator, finding room for it might be a problem, but a Borla XR1 4" inlet/outlet will probably fix your problem, it is what big power, mk4 supra owners use, again with no flow restrictions.

Holy thread revival batman!
So the car has been getting a lot of attention. Fully rebuilt coilovers with new ride height and geo set up, full service (every drop of fluid changed) and various other tidy up jobs (new badges etc).
It also had a video shoot with YouTube FN Lew, looking forward to seeing the end product when it's uploaded.
