so... what will actually be the better route to take

(2) t25's running off true duals
or
(1) t28 off the stock 2.5" exhaust
or
something different?



other questions:

1. how well does the trunk breath?
2. would 5-6 psi be beyond a tunable range on a 11.5:1 compression motor w/ 93 octane fuel?*
3. " 8-9 psi " " " w/ 110 octane fuel?*



*injectors, MAF, TB, fuel pump, will all be up-sized and car will be tuned
