It's not that bad on the highway from what I'm told, you can hear yourself think, but it's close to if not more than 100db... It's straight thru 3.14" catless with 1 muffler, it'll be loud enough but it's very aggressive and deep, with a nice idle

 

greddy ti-c race or whatever it's called

 

Removed.

 

seems like the duals give out more power... but duals on a 4 banger?

 

this is the competition Ti-C... im pretty sure this is exactly what your looking for, and as far as the whole dual tip, single tip debate, i used to have an SRT-4 and it was commonly debated, and the single tip exhausts are what are usually on the high power cars, the dual tip is just an extra bend and extra weight, and they flow almost identically... remember that

 

Is there one exhaust that makes more power than any other, or are the like any car and make 5- + hp of one another?

 

ultimate racing is the best out there. i just got my full turbo back and it was the best purchase i ever made. go with them

 

It looks like even the Competition version necks down where it would meet up with the O2 housing.

 

NO bottle necks, no reducers, no resonators or restictions in any of our exhausts for the EVO's.

 

yea, because the 02 housing isnt 3" itself...

 

I have the full ETS TB exhaust on my car.It dosen`t drone at highway speeds and sounds really deep at idle.Their TB comes with a 02 DP,TP,CB.Most DP with 02 dump are over $400 alone.PM if you want any pictures or sound clips.
