@ShawnSubaru Yes, the downpipe (exhaust immediately after the turbo) is what free's up the power on this car. It will require a tune, but you should see significant gains in power. The cat back makes very little difference in power, but a significant difference in sound. Even on a 400+ WHP setup, the stock cat back exhaust does not pose a significant restriction.

@johnpark219 That's simply the turbo spinning down. That can be heard if you install an aftermarket downpipe (catless or catted) and a aftermarket cat back.

@garrettej8 The COBB downpipe is catted. It does not need any adapter to be installed on the stock or SPT exhaust.

@Ollie100111 on a turbo car, it makes a nice difference on power, but only with a tune. In his case he is using the cobb access port to reflash his car. so maybe about 15 to 20 WHP. something you can definitely feel.

i like the subaru rally sound that all subaru sti or wrxs should have. you have fun with your muscle car.

That scene at the end makes me wish I was still living in PA. :( Georgia doesn't get a whole lot of snow, so I won't have as much fun with my new WRX when I get it. It'll still be a blast, but that car is meant to take on the snow along with the other elements.

@fickel88 You are right....the 08 to 11 wrx difference is huge and I realize the 11 wrx is not much different than the you will notice I only mentioned the traction control and differential button setup as the main reasons to get the sti....the sti allows you to drive like a maniac and get away with it...the wrx I wouldnt have the confidence to drive the way I have driven in my sti....plus the brembos are insane. Though I do have the roads to take advantage of the sti's features...

Very nice video, thanks for posting. Sounds only slightly different than my 2010 with an Invidia dp and SPT catback. Very nice.

I ended up buying an evo, trying to find a white STI in Texas was too tough. Couldn't be happier

@ Clark - I also have the same set up in my 2013 wrx sedan. I was able to use the stock donut gasket on the mid pipe to the downpipe. Hope this helps, laters.

@nordicjim He has General Altimax Arctic tires in 215/55R16 on black steelies.

@Robflesh haha yea just got mine a couple months ago too. i love it!
enjoy your ride! :D

[Robflesh]

@Chonj92 Hell yeah! Too bad I didn't take advantage of that opportunity. :( I was impressed how well I was able to go up some icy hills. I thought I'd be screwed because of the summer tires, but I had no problems. I have over 230 miles on my new Scooby, so I got awhile before it's broken in.

[Ollie]

@ShawnSubaru Okay. See that is the best explanation I've heard. And so a "Cat-back" retains the catalytic converter and just changes the rest of the exhaust from the catalytic converter "back?"

[Turbosauce]

sounds perfect, I want mine to sound like that! Quick question, is the cobb downpipe you installed catless? Also does it bolt right up to the SPT exhaust or do I need an adaptor?

[dehydrated_HO]

it'd be sweet if you could do a video comparison of the stg1/stg2 spt downpipe setup. i tried to play the relevant parts of your videos back-to-back, but it doesn't quite work.

[fickel]

@grove1104 Lucky, Kansas is (thumbs down) for hills and twists. Don't get me wrong I love the STI and it is perfect for that time you push the car hard, not to mention the rock solid tranny. What have you done to your STI, or is it kept stock?

[ptak]

Nothing really "voids" your warranty per se but claims can be denied if they can determine a mod led to or caused the problem that occurred. By the way, the Cobb OTS maps require that you use a catted DP not catless.

[mer]

Are you happy with the WRX. Im trying to decide whether to buy the WRX that is at my local dealership or order an STI.

[Chonj]

@Robflesh Haha we just got a whole LOAD of snow here in GA!
snownuts in the parking lot!!!
