MAS, throttle body and exhaust help?

Can anyone recommend a MAS and throttle body for my motor? I am running a LS1 with a innercooled MagnaCharger, at 9 psi. It has a blower cam and LS6 heads. I am running 468hp at the rear wheels with the stock MAS and throttlebody. I was also curoius what you guys thought I need for exhaust as well. I currently have 1 5/8 headers and 2.5 pipes.

Any input would be greatly appreciated.

Hey man...I'm putting down close to 600 with a 04 LS1 on a stock 04 MAF.....I did have Mark Shaner port the stock TB...man what a difference! Running 1 7/8 headers into 3" pipes.....There are a few aftermarket MAF's I have seen the 04's use.... http://www.slponline.com/browse_list.asp
I see you have a 69...what year LS1 are we talking about?

you do not need a new maf. the stock one is fine. as for TB's shaner, mti, fms, tsp and quite a few other places offer porting services. That or you could just port your own. not too difficult. I dont see it netting you much hp with the blower and all, but if you wanna do it, cool. Are you running shorties? most headers ive seen 1 5/8 are hooker shorties if im not mistaken.
