Slightly leftfield, but have you thought of improving induction noise rather than exhaust?
A drilled airbox lid would be less intrusive than an exhaust with no resonance/droning concerns; part throttle would sound like normal, but you'd get a V8 roar at WOT. Easily reversible if you get a spare lid/box.
Once i've bought a replacement drill, this is my plan of action.
