Default 2.5" or 3" downpipe?

what up? I have a 99'Integra LS with 94 GSR swap, my buddie just put T3 turbo in few weeks ago, so now I have few questions for ya'll, before my car under N/A, my apexi N1 was really loud, sounds good, but since I got the turbo, its quiet as hell, I have 2.5" turbo downpipe welded together with my testpipe, and the testpipe connect together with the exhaust piping, so would my be louder if I get a 3" downpipe with like apexi GT spec exhaust or a custom 3" exhaust pipe with the N1 muffler?
question 2: I have stock igniton now, should I get the MSD 6 BTM racing ignition?

question 3: whats the best size of injectors I need? I running 7psi boost daily, and my local hondata tuner told me I have to get a set of 440cc injectors before I get the car dyno and tune.

1. why do you want your exhaust louder? A turbo quites the exhaust down alot.

2. what fuel management are you running? stock will more then likely be fine (dif. plugs)

3. 440s would be plenty

Umm if you are refering to Open Downpipe, it's not too loud. It's for sure not as loud as open header. A LOT of people run open DP around hear and never have problems. and if you like it loud that's will be perfect for you.

Bull ****. Soon as any cop hears you not at greater than 5% throttle his *** will pull you over in a heartbeat.

I let my friend drive my car at night, and i could hear it for miles. Granted it was quiet in suburbia, but for miles i hear it brooming away. The floor shakes with the pulses its so ******* loud. Its sooo rediculously loud. I can't believe i've read people say they run an open downpipe and haven't had any trouble.

I have been running open downpipe for months now. Drove past some off the worst cops in the area at half throttle... no problems.

And its not that loud either.
