All in all, it's not impossible with the wheels on. However, the innermost mounting point uses a Phillips head screw on each flap. I wish they had used hex heads because you are NOT getting a screwdriver in there with the wheels on. I cheated and used a pair of pliers to grip the screw.
Also, I would suggest bending the innermost mounting point for the rear flaps up a bit once the bracket is installed. The inner edge of my flaps are about 1/2 an inch lower than the outer corner. I'll have to go back at some point and adjust them.
Other than that, I just took my time. The last thing you want to do is break one of those [sarcasm]amazingly sturdy[/sarcasm] plastic clips Subaru uses.

I picked up some stainless steel hardware to install my CNT catback this weekend.
However, that plan got put on hold since none of the auto parts stores seem to carry the exhaust gaskets I need.
Does anyone have any suggestions? I already checked the CNT site and they do not offer the gaskets. I am tempted to lug one of the pipes to my dealer and see if any of the OEM gaskets would fit.

Summitracing.com sells the vibrant exhaust gaskets that will work for that exhaust.

Thanks for the tip. I actually called CNT after work (yay for calling a timezone that is 3 hours behind!) and was able to order them. $40 shipped; not too bad in my opinion.

I have to say, I am very impressed with the Subaru vendors I have dealt with so far. CNT Racing had the gaskets and GrimmSpeed just went above and beyond on my latest order. The whole Subaru community is simply amazing.

Okay, there is fast, and then there is "how in the world did that get here in one day from California?!" fast. If you couldn't tell, the exhaust gaskets I ordered from CNT on Wednesday evening arrived today. I thought I was going to be waiting for 2 weeks. Like I said before, the Subaru vendors always manage to amaze me. Anyway, I know what I'm installing this weekend!

In other news. I racked up my first 5,000 miles in a little over 2 months.

I installed the CNT catback today and man is it nice to have the rumble back!
Other than a bolt that got cross-threaded and some minor fitment issues, the install went smoothly.
I will get a sound clip posted as soon as I figure out how to get the video off of the non-SD card that the camera uses....

As promised, below is the sound clip of my new CNT exhaust.
The video quality is kind of low, but it's the sound that we're interested anyway.
I tried to embed the video, but copy/pasting the link as some here suggested didn't work. *Shrug*

Today was the first 70-degree day we've had so far this spring.
Therefore, I took full advantage of it and attached my badge of ownership!
I also snapped a few extra pictures of the car outside of the garage.

It's cool that there's a 48 Hours badge. I guess I have to update mine from 4th to 5th and add some stuff to mine.

Where in NJ are you? Always trying to see who's local to me.

Ooh, I see there's a bit of Q&A going on since I last logged in!

@ 701WRX & astr1x
Considering the CNT costs about $500 (when most catbacks cost $1K+), I really have no room to say anything negative about it. The welds are great, it sounds awesome, and the drone isn't bad at all. Then again, I've never sat in the back of my car, so who knows if my passengers would agree.
Also, the guys at CNT are the best! I bought this unit secondhand and was in need of the exhaust gaskets. I called up CNT and they had the 3 gaskets (plus all of the hardware) shipped to me, for $40, in 2 days, from California. You just can't beat that!

There are a few small gripes I have.
• First, I had some minor alignment issues with the stock catalytic converter, but nothing widening the holes on the converter flange by a hair didn't fix.
• Second, like several people have stated on the CNT website, the muffler tends to sit deeper on the passenger's so that (looking from the top of the car) it's twisted counter-clockwise a bit. You can see it in the picture of the muffler from my previous post. I'm going to try pulling the rubber exhaust hangers all the way to one end, then put small hose clamps on the hanger rods to keep them from sliding back.
• Finally, if the conditions are just, just right, I do hear a few knocks every now and again. But, what do you expect when you slap 3" pipes onto a car that came stock with 2.5"? In any case, the more I drive the car, the less often it happens.

I would in no way consider these deal-breakers, though. They are really just minor quirks of an aftermarket exhaust with a sound that truly rivals that of catbacks which cost twice as much! If I hadn't found it used on NASIOC, I would definitely buy this catback new!

@the mike
The only way you'll get a 48hrs of Tristate badge is if you go on the January 2015 trip.
Subaru had a ton of these things made up for our trip in 2013. This year we handed then out to all of the new participants, so they're only available while supplies last.
I'm in northern NJ, about 15 minutes south of the Warwick NY state border. You?

Now that I've rambled on about that, does anyone have tips for swapping out the engine pitch mount? From what I've researched, you simply pull the stock intercooler off, swap out the mount, and reinstall the intercooler.
However, knowing how sensitive the turbo boxers can be, I don't want to screw anything up....

Actually southern NJ, right outside of Philly. I have a lot of intentions of doing the 48 hours, bit things like newborns keep getting in the way. I just picked up my 4th WRX, so hopefully I can make some meets/events this year.

Thanks for the reply. I ended up buying the CNT catback and installing it already (I reused those damn spring bolts...). I really do like it, but i feel like my 3rd gear isnt pulling the same way it did with the stock.

I am glad to hear you like the exhaust! I didn't notice any performance loss when I installed mine (if anything you should gain power).
However, after installing the CNT on my WRX, I have noticed that when I mash the throttle, right around 4K RPMs there's an airy whistle. This sound is different from the sound of the turbo spooling up. I'm hoping that it's just because of the wider tubing; I would hate to have a boost leak already....
Anyway, every car reacts differently I guess. Do you have any other mods on the car that might conflict with the high-flow exhaust?

Well, it took 3 years, but I finally installed the Kartboy engine pitch mount I won on the 2011 48hrs of Tristate! My old Forester didn't have one, so it's just been sitting.
Removing the intercooler was easy enough. Reinstalling it... not so much. I had to put a very thin layer of grease on the outlet to the engine to get the rubber hose back on and I snapped a bolt on the bypass valve (it wasn't even that tight). Luckily, being a new car, I easily got the stub out of the intercooler and found a replacement bolt.

The results: engine noise is more pronounced at start-up, but the car coasts much more smoothly and definitely has a little bit of extra pep since the torquing has been restricted.

Anyway, pictures!

Yah, i think i have heard that as well, so im thinking/hoping its not a leak. No, its stock except for a drop in filter. I think its just me being over aware or something..

In that case, since we're both hearing the same thing, I'm just going to assume it's because the airflow after the converters has changed.
If my engine ever detonates, you'll be the first person I tell!

When you took off your factory CBE was there any type of gasket from the long-pipe to the mid-pipe(one with the cat). And did you put a gasket between the mid-pipe and the new CNT long-pipe?

When I removed the stock CBE, there was a donut gasket between the second cat and the long pipe that lead to the muffler.
Since the CNT has that flex pipe to do the job of the donut, I just drilled the holes in the flange on the rear cat a little bigger and used the flange gasket and bolts I got from CNT.
To answer your question, yes, I did. Why do you ask?

I know you only put it in last week, but I'm curious about how you like the pitch stop? I do a lot of city driving so I was thinking about picking one up but am hesitant due to some people saying the cabin NVH is pretty bad. Awesome build so far! And thanks for all the info

Yes, that does answer it. I left that donut gasket in and man was that a bitch to work around.. I may have to lift her up again and remove that. Or do you think it wouldnt matter.

Honestly, if you're driving a WRX/STi, chances are your car is going to be loud anyway!
In all seriousness, though, the noise isn't that bad (to me at least). It's loudest when starting the car... which takes about 3 seconds at most. It almost sounds like you are listening to the starter through a stethoscope. Once the inner workings of the engine start making noise, though, I hardly notice any difference. I might notice some extra noise here and there while in motion, but again, the exhaust, radio, and wind passing by the car make it pretty hard to hear unless you actively listen for it.

In my opinion, the pitch stop is totally worth doing. I can't even begin to describe the number of advantages I have noticed so far... but I'll try.
• The car bucks much less while inching through traffic and while coasting at higher RPMs
• The clutch is more consistent
• Acceleration is improved ever so slightly and throttle response is increased (less engine torquing means more power to the transmission)
• Gas mileage is improved ever so slightly (again, less wasted power)
• Handling is improved, believe it or not. Since the engine is more stationary, there is less weight transferring from side to side under the hood through the bends. Also, this means that the axles and drive shaft stay in a more consistent position (stiffer transmission mounts would probably affect this more, though). Overall, I have noticed that turn-in response is definitely improved.

Since that first pipe has the flex point in the middle of it, that might not be a bad idea. The flange on that pipe isn't meant for a donut gasket anyway. They may have changed the design since mine was manufactured, but I doubt it.
