Default Best quiet muffler?

I have an 06 2.5i. I wanted to get a muffler for it, not a really loud one tho. One that can give out a lower range sound along with sum performance. Does anyone know any they can recommend? I understand that there are no turbo on this car, therefore the sound might be a lil different than WRX, but still, one that sounds good. I also have an HKS intake, does it affect the sound? If u do have a sugguestion, please let me know. If u know the price and where i can get it, it would be amazing. THX all.

Prodrive Oval or Prodrive Round-Tip

You can find them at www.oakos.com (my favorite site for Subaru stuff), for $339 with free shipping. Standard price you'll find all around, but Oakos takes good care of you.

Prodrive is actually sort of loud. It's nothing compared to the mellon shooters, N1, HKS, etc, but its fairly loud if you want something "quiet" but louder than stock. Evo2 is probably a good bet if you want low rumble and bass without a lot of volume and the hush is good if you want the performance with minimal increase in sound. Get high flow cat pipe too and it will increase the volume of the hush. That said, if you use a wrx exhaust like I mentioned you need a muffler guy to fab up some flanges to connect it to the 2.5i exhaust, I dont believe it will fit even remotely without some fabrication. I don't know much about rs/I exhausts other than that so hopefully I was of some help.

+1 for Prodrive. I had one on my wagon for a while. I wanted something louder so I got a Magnaflow and it was too loud. I have a Blitz Touring now and it sounds great but the tip is too big. Also check out the Borla Hush or Greddy SP2.

I have a Prodrive and it is a nice low sound. It really brings out the Subaru rumble that most of us love. It's really only loud at WOT.

AFAIK, the 06 2.5i uses the same flange for the axleback as the WRX. So, any axleback for the WRX should fit the 06 2.5i. That said, a catback made for the WRX will not fit, as the midpipe is about 4in too short, however it can be modified by an exhaust shop fairly easily.

Not sure where you got your info from, but the hush is louder than the prodrives.

Here is a question on topic from someone who wants to do an exhaust himself...Is there any welding involved or is it strictly bolt on?

If you buy one designed for your car, it is strictly bolt on.

Going catless will make it extremely loud unless you get a fair sized resonator welded in the midpipe.

Catless up and down pipe with the STI catback is fairly quite, until you hit the gas. I have not had any problems with the law, and it looks stocks. Also I have the wagon so drone was a big problem that I had to over come. The setup listed works for me with drone and handles my stage 2 without problems.

Thank you all for the feedbacks. But I'm leaning more towards the Greddy EvoII or Borla Hush (Running Catless would be my option first to see how it sounds). I heard a Greddy driveby, sounds pretty good. A lil louder than running Cats but acceptable. Borla Hush seems to be quiter and provides more performance than Greddy, can't really decide, but one of those two.

Prodrives are great, I love them. They're 2.5" though and your car should probably get a 2.25" exhaust since it's non-turbo...

But that's an old argument. I say the Stromung exhaust, go to Rich at www.daddysscp.com or Dale at www.boxer4racing.com.

Add another one to the Prodrive Ovaltip list. Helps you stay under the radar.

..except this is on the NA forum and we don't have up and down pipes.

But if it works well on the turbo cars, one would think that is should work well on the NA cars.

Generally, NA exhausts are louder I believe.

HKS intake is installed a while back. Don't really like it. Doesn't sound that great compared to my other old ones. I prefer APS. Sounds much better with a deeper kinda roar, but thats sound only.
I personally thought 2.5i have the same cat backs as a WRX is it not? Only STi has a different cat for the 06 model. Thats what i thought.
