Default Borla Catback & Perrin Pulley on 05 RS **Video Added**

I finally installed my Borla catback on my wagon. It's the 14885 catback from Borla, they list it for all 96-01 2.2 and 2.5L Impreza's, but fit almost perfectly. The hanger right behind the muffler is wrong and you can't place a hanger on it, but I used Cobb urethane hangers for the midpipe spot and the two rear spot, and there's absolutely no movement whatsoever, so I think I'm going to leave that hanger behind the muffler alone. And the Cobb hangers came in Blue!

Also, the bolts are no where near long enough, like not even close. The flange on the midpipe that connects to the catpipe is a floating flange, not welded down. So really, if you were looking for a conservative exhaust for a WRX, this would bolt up with no issues. The flange is also VERY thick, I'd say 3/8 - 1/2". The end is flared and mates up to the catpipe outlight very nicely. For bolts, I ended up using the stockers, but had to remove the springs on the stock bolts, then everything bolted up nicely. As I said in my other thread, the axelback section isn't flanged, it's got a flared section that slides over the end of the midpipe and a stainless band clamp cinches it down. The clamp is very heavy duty and it works well. I mounted the midpipe including the hanger, then from the back, shoved the axelback portion on, slid on like butter, and tightened the clamp. Was a very very easy install.

So, sound... I have a video, but putfile isn't letting me upload, says it's under maintenance right now, so I'll post it up when I can upload it. I love it. I'd heard this was the quietest catback out there, and because I also got Borla-replica headers, and drive a ton of highway, I wanted a quiet system. I haven't installed the headers yet, so right now it's very mellow and deep. When you're hard on it it pulses like a boxer should, though not as defined as with headers. On the highway (70mph/2900rpm), the sound is there behind you...but I wouldn't even call it drone. It's back there, but it's not drilling into the back of your head. Keep in mind, this is a wagon. I think in a sedan or coupe you wouldn't hear a damn thing on the highway. Personally I love the sound, it's perfect, exactly what I wanted.

I can't really give an accurate assessment of power gains, because I installed a Perrin lightweight crank pulley at the same time. I've noticed improvement off the line. Rev-matching is much snappier and all-around drivability is much much better. It's a lot easier to drive more smoothly, as I've always found the tranny a bit of a beast to drive smooth. I attribute all of this to the Perrin pulley as that's what it does, but the catback no doubt enhanced the Pulley's inherent benefits. Drawbacks? None. Buttery smooth as if that big heavy stock pulley was on there, all the way up to redline. Hammering gears under hard acceleration is much smoother and the revs pick up much faster when you get your foot back to the floor. I'd say a lightweight pulley is one of those only-good-things, no-bad-things mods, along with the ground kit. As for the install, my 05 stock pulley slipped off like butter once I cracked the crank bolt loose (that was no picnic) but an older car might have troubles. The procedure is simple as pie, just takes muscle.

Borla Catback:
Fit & Finish: 4.5/5.0 (would be 5/5 if they sent longer bolts)
Appearance: 4.5/5.0 (I thought the tip was too big, turns out, it's perfect...muffler not polished)
Sound: 5.0/5.0 (considering catbacks only)
Performance: n/a
Install Difficulty: Easy

Perrin Pulley:
Fit & Finish: 5.0/5.0
Appearance: 4.0/5.0 (a pretty blue color would be nice, but now I'm nitpicking)
Performance: 5.0/5.0
Install Difficulty: Easy-Moderate

Cobb Hangers:
Fit & Finish: 5.0/5.0
Appearance: 5.0/5.0
Install Difficulty: Easy

Video to come when putfile lets me in. Pictures to come when the sun comes back up.

Also, I didn't get around to doing the headers tonight as it was getting late. I hope to get a chance to bolt them up next week sometime to get some video footage of the whole works.

Sweet, definitely going to come alive once the headers are on. The sound should be what you are looking for.

Here's the Video! This is before the pulley was installed. My apologies for doing it while the car was in the garage, kinda echoed a little...

No, I used a digital camera with video capabilities. And without hearing them in person, it's impossible to make a declaration as to whose is deeper/sounds nicer, since any microphone along with whatever audio compression is used will distort the sound over the actual real life sound. I'm content to say, I can promise mine's quieter.

Please excuse the dirty car, it's been hovering around the freezing point and hasn't stopped snowing for days.
