Some c70 questions for the gurus

[Sparkysparks]

Edit. Title is meant to sar for the gurus.
So i have just got this lovely saffron c70.
Couldnt help myself and took the airbox off and blanked off the recirc for some chatter. Removed the carbon canister lines. My next step would be turn boost up and remove the boost solenoid replacing with a mbc.
Any problems with this on the me7?

Also. Not looked under the car yet but what is the stock bore exhaust pipe size.

And do v70 grills fit as they seem to be cheaper to get hold of.

I will get some pics of the car in a thread tomorrow as its probably one of the nicest cars ive owned. For now. Might be a different story when the coilovers come
