Official Exhaust Thread

Just curious, does anyone have a decibal meter or some sound measuring device to claim what is "loud" or "quite quiet"? I know that the iphones have an application (sorry it has to be jailbroken) that has a decibal meter and can read up to 180. If someone can get a reading of their cabin and list what item they have installed, then I think it will be a better reference than subjective opinion? I'm wanting to do the header and exhaust, but if I can't hear my thoughts when I drive I'm going to hit someone.
 
^^^ If you think it's going to be too loud then it's going to be too loud for you. Don't bother with an exhaust if you can't accept the noise. I say "noise" because that is what you are going to get with a header and an exhaust.
 
does anyone know how t get that backfire noise? like when you let off the gas or downshift? i LOVE that noise
 
damn, that probably isnt too good for the engine then. theres an srt4 that passes the store i work at everyday as im taking in the displays outside, and it has it. sounds so cool
 
my miata has a cat and it burbles and pops all the time. It does it w/ the stock ecu and when we had a rough tune on the megasquirt. They, like the protege, just run rich.

Then again, this is my cat and cat-back... so it helps. There's about zero restriction in the muffler :D

I have a custom OBX muffler with 2.5 inches all the way to an obx header. It's loud as hell and everyone hates me on the road! yay (lick)
