Sound Decibles.. T2 vs NA: Full aftermarket exhaust

Say you have a T2 and an NA with full after market exhaust, I know the T2 will be quieter, but how much? Its because of the Turbo manifold im guessing. I just want to know what to expect, cuz im ******* sick of my sound decibles matching my horsepower.

From what I understand the turbo is quieter than an n/a with full exhaust (assuming full exhaust on an n/a is with a header).

The turbo muffles sound well.

Not as loud as my n/a with RB header, no presilencer (straight pipe instead) and dual ebay mufflers

Honestly, you'll get used to it. If you get a good muffler, or two, it'll be just fine. My friend has a TII with no cats, ~3" piping and 1 muffler, and its not bad at all, really not even loud. Just gotta find the right muffler/s.

I have an 88 turboII with a 2.5" DP, 3" main cat replacement pipe, into the stock y pipe and mufflers (i know, eww) but it isnt even loud at all. Much quieter than my brothers supra which has a fully stock exhaust with only a slight cat leak.

Now what if i were going to throw on some magnaflow duals, how loud would we be talking?
