She'll Buff Out
If you're not going to go with a bigger turbo or a better tune, you might want to stick with the stock diverter valve. It will be more efficient than a blow off valve and since you're not going to be running higher boost, it won't damage your engine. Now if you go with a big turbo, injectors, and agressive programming, I'd definitely choose the BOV.
I wouldnt go all out like that cuz its a auto and its already up there in mileage deff dont want to start beating it, which i would want too. you made a good point, so exhaust just cuz i like they way they sound lol and intake.
