Default Supercharged exhaust size

I have a built 6l with LSA heads and 2" headers . I plan on 20lbs of boost . What would be a good exhaust to use on a 99 TA . Dual 3" , or a single 4" all the way back and split in to duals ?

Dual 3" all the way back, especially since you the headers already. That's what I'm doing

I have no idea how you would fit either one. With supercharged FI instead of turbo, there is no such thing as too big exhaust. The maximum that will fit for enough clearance is always the best answer. That seems to make 4" better.

If you ran a mufflex 4" exhaust with a magnaflow it would be fairly quiet driving around vs dumps.

I was looking for the best flow , and i am not worried about the noise at all .LOL Cops might , but I am not ! i was thinking the 4" with a spintech , or just a bullet muffler like a loud mouth has and y the rear to dual 4' for the rear .

If "too loud" is not in your vocabulary, Kooks 3" system.
Great flow & the x-pipe is an added bonus for smooth sound, not to mention the scavenging effect small as it may be it does exist.
Pretty sure Maryland Speed has the system on sale as we speak.
