I keep reading that the exhaust is only a sound modification, how true is this? does anyone have any proof? Why is it in some magazines like motor trend they say the combination of cai and exhaust give some extra 30horse. if the exhaust is nothing but a sound mod would they not say that with a simple cai change it gives you an extra 30horse? Has anybody done a dyno with only the cai? then one with only the exhaust? then one with both? proving that the exhaust does nothing. im just having a hard time believing the exhaust is only a sound modification.

I've seen a lot of downplaying of certain mods as "not worth the money". I think much of it stems from the fact you gain so much from the CAI that it makes other mods seem less worthy for the dollar.
I got the CAI, but I want the full Corksport set up. Of all the ones I've heard, it sounds the best IMHO. I still want to hear the HKS, but I can't find sound clips of it anywhere.
read it in sports compact car when they first tested the car, the mazda techs stated it is the CAI where you are getting the gains and not through the exhaust.
Thats my vid...just go back to the link and click more from this user. I have a few of me running it with the two front windows down....I love this system.

Buy the Mazdaspeed exhaust. You can always add a DP or test pipe later. Even if it doesn't add a lot of HP you'll love the sound and you'll keep your warranty.
you will get more gains with a downpipe or turbo back exhaust for sure. but when i changed my cat back on my wrx 06 def felt a difference in time for turbo to spool up. It seemed to spool up Noticeably faster than stock. I put the stock exhaust on and off a few times because i had to replace the catback because of defects. and each time i put the cat back from a stock exhaust noticed a quicker spooling of the turbo.
So even though peopel say you dont gain any HP I doubt that. Prob not as much as an intake but it does do something.
