Make your car loud?
Never heard that, rather, worse...make your car boost spike/creep (I forget which).
Having a MP and a DP with a Catback is too manipulative to the exhaust airflow and will mess with your turbo's. The only way to have all 3 and be safe is some sort of ECU & Boost controller.
A DP & CB is the safer bet.

oh...btw you wont get much out of the DP, MP and CB if you don't install an intake...but then you must get an upgraded ECU...and upgrade the fuel system...and...etc...

A boost controller wont stop boost creep, you'll need to port your wastegate to stop that. But just order a dp/mp combo from rx7store or somewhere and youll be ok, just make sure to replace all the studs and gaskets while your under there.

the fact is the car can run at 10 psi with a intake and full exhaust. the a/f ratios are on wade's site some cars will creep some do not, you will have to set the controller be cautious. a full exhaust WILL be loud no way around it. dp, high flow cat and cat back will be enviro friendly and relativly quiet.
