Louie, is yours a GR or GV? I do get that same "GRAAAAANCH" when I'm WOT in my car with the catted DP. It may just be a bit more pronounced with the catless.

If you have an exhaust leak anywhere with a catless dp most likely the fumes are going to be going into your cabin when driving around in the city. Just my .02
You make it sound like your pumping sarin gas out of the tail-pipe. If you scale your car against the millions on the road, your emission foot-print is pretty small (I know I'm stretching this pretty far). I understand your point and it is valid; however, the emissions coming from your catted exhaust is just as poisonous as my uncatted emissions... just food for thought.

And momentary fireballs isn't going to melt your bumper, its not a flame thrower. You can check my bumper for 18k miles of fireballs (I've only had after-fire pops only when tracking the car).

And for what it's worth, I went catted. You will still smell the exhaust more than you do with the stock DP because the aftermarket DP is freer flowing and doesn't filter exhaust fumes like stock. But it's not ridiculous.

Catless does add more rasp. A friend of mine had a sedan with the Q300 as well and his is catless, definitely more rasp than mine. Another friend was catless with the Q300 but El headers, it was so raspy it was ridiculous. It sounded like an entire different cbe was on it. Crazy how parts change the sound that much.

I believe the sedan is a GV while the hatch is a GR. Don't trust myself on that so...

From Wikipedia:

The new Impreza was offered as a five-door hatchback (designated GH), with the four-door sedan (designated GE) introduced in 2008. The wide-body variants of the hatchback and sedan are labelled GR and GV, respectively.

Well.... Eh, thanks I guess. Good luck finding parts in GV searches. I don't think I've seen enough to make wonder what the GV designated.

But I guess it's good to know.

2011 WRX Hatchback - Various catback exhausts.

SPT Exhaust


Stock Exhaust


Differences. SPT on right and stock on left. No resonator on the SPT exhaust. Double walled tips on SPT.



And my new instrument of destruction - the TurboXS GT Catback:

Good choice on that cbe. It sounds nice with a very bassy tone.

Here is some info on installing that cbe I posted earlier in the thread. Hopefully this makes sense and helps if you run into problems installing it. It's not a very hard install though.

The stock spring bolts still fit in the mid pipe/Dp connection. I put the spring bolts through the turbo xs mid pipe (without spring on it) first, then turned them so that the shoulder of the bolt would wear down slightly and fit through the flange better, then put the spring on it. The spring bolts on the rear are a similar issue, you might have to take a small file and clean out the mounting holes on the flange so that the spring bolt can slide through the flange holes. A dab of oil on the shoulder of the bolts would help.

It provides the signature UEL rumble and from the interior, it actually sounds quieter than the SPT I had before (less resonance/drone, maybe?). It's a good system for the price I paid for it. It ran me $604 for the exhaust from Spun Autosports, then about $20 for a rubber mallet to beat the heat shield into submission (so it doesn't come into contact with the flex joint) and two bolts, two nuts, six or so washers. Idle is barely noticeable over the stock exhaust, except in the lower frequencies (more bass).

I haven't broken it in yet since I just put it on today but my impression is that it looks much louder than it sounds. Firing the car up is a much quieter affair, compared to the SPT.

Absolutely, time permitting tomorrow I should have something up with a real camera. Also, I'm considering using some protools recording gear to get a high quality sound clip. That would take some time so let me know if anyone is interested in that.

It was recorded on a cell phone it's actually louder in person. I should have a higher quality sound clip available this week. I am still fighting with the tips, they are supposed to be flush, I'm not sure why they are out so far. I'm going to mess with that more tomorrow.

Ionoo-

Pull your car out of the garage and place your camera about 5-8 feet behind the the car at tail pipe height. Phones actually have decent microphones in them but are meant to pick up sounds that are direct. I have compared several phones, cameras, go pro, and contours... They really all sound about the same. A higher end microphone will probably pick up more ambient noise..unless you can cancel it all out post.

Good luck

So I spent a solid day working with EFI logics to find a solution to the 2011+ WRX/STI Sedan CBE tip alignment problem for my Cobb prototype. We came to the conclusion that it was welded incorrectly so naturally before personal fabrication I contacted Cobb. Within 24 hours Cobb has a replacement exhaust being shipped from CA to CT. Moreover, this replace is a production product, NOT PROTOTYPE, prepare for the release!!
