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.

 

a turbo is a great muffler... my exhaust is about as quiet as they come... 3"dp to 2.5" cb... 2 resornators inline. I kinda want a 3" cb tho..

 

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.

 

lets say that you get a downpipe and replae the cat with a straight pipe. how loud are we talking? turbo car of course.

 

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?

 

well i had a half bridge and 3 inch exhaust before this so i dont think noise is much of an issue

 

I have Streetported t2 with a 3inch Mind Train DP/MP and corksport catback and its the loudest car Kevin Landers has ever had at his shop.
Corksport = loud as fu*k
