I went for the Milltek DP and sports cat (200 cell) and then mated that to a supersprint cat-back with a slight custom-made reducer (from 3" to 2.75 i think)
Whole system cost about £680 i think.
A cat-back won't do IMO - you'll still be restricted by standard cat/dp.
If my car boosted to 28psi i think i'd refuse to drive it until it was sorted. I am panicking about my 22/23psi peaks i see on mine - 28 sounds rediculous
EDIT - isn't 28psi something like 1.8/1.9 bar??? I know of 500-600bhp cars that run far less than that!
