I am looking into getting a my04 WRX and wanted to get an exhaust for it. Im not looking for a crazy 3 inch turboback, just a nicer sounding muffler. I know the usdm STI muffler is quite pricey but i wanted to know how it would sound to just have that muffler on a stock rex. would it resemble the sounds of the STi or would it basically not change? i was also thinking about the Prodrive muffler, i have heard good things about it and i was wondering how it sounded as well. Compared to one another, which is louder, or "better sounding" i love the rattle of the boxer engine from hearing STi's and i was wondering if either of those pieces would help to create that low rumble. any responses welcome, thank you all!

 

Might want to post in the WRX PowerPlant next time.

 

sry i just thought it was a pretty general question since i was just looking for some opinions. if a moderator could move the thread i would much appreciate it.

 

as far as sound goes, do you want a louder one or a quieter one? with the sti muffler your not gonna get the same sound as a sti but it will be a little louder than stock, im not too sure about the prodirve exhaust. What i would recommand would be the hks hi-power catback

 

the hks is way loud though isnt it? i was looking for a much more subtle sound like the stock STi, so quieter, to answer your question

btw.. gracias to los moderators for moving this

 

Borla Hush catback, its a dual tip, nice 3" exhaust, i just hear from other people it is not as loud as the HKS or Helix's.

 

I would have to say for you to get the Prodrive over the STi. For one the Prodrive will sound a little bit louder but you wont even hear it drone inside the car. and it looks better IMO Good Luck either way

 

Here is a post that has a comparison of the prodrive and stock axel back http://forums.nasioc.com/forums/showthread.php?t=628963. Looks like the Prodrive meets your criteria.

 

thank you all for the replies, does anyone happen to have a sound clip of either of these exhausts. i have used the search function so please dont flame me to death, but if anyone could post a video or sould clip it would be much appreciated.

 

My new favorite is the APS 3" piece, but this is only available (AFAIK) as a turboback. A friend has one, and it sounds as quiet as stock when you are idling or just putting around under 2.6k, but when you go WOT it screams like something recently unleashed from hell. I'm certain a Civic owner wets their pants every time he fires that thing up.

 

I have had both pipes on my car, Prodrive is definitely louder. Sti is only slightly louder than stock but deeper tone, should sound like an Sti if that's what you're after, rest of the exhaust is pretty much the same. Power by buttdyno is about the same for both pipes. IMO a used Sti pipe for $200 is pretty hard to beat.

 

I have the prodrive oval tip...the sound is so sexy.

 

Prodrive muffle is definitley more aggressive sounding than STi, but still subtle. None of the big mufller/tailpipe blues. I have had the prodrive for over a year......no drone, my neighbors don't hate it, yet it sounds throaty and has a good rumble from idle on up. Not much (if any) performance change....but sounds like the car should have stock. And it looks subtle too....not flashy and offensive.
