Ease of Installation Price/Value Quality "Just installed it a few days ago along with a Volant cold air intake, swapped out my K&N intake and MagnaFlow exhaust (had those in for 5 years), haven't noticed a change in mpg yet, but sure does sound better and power to the wheels feels stronger...Highly recommend."

If you have a ramp or hoist it makes the installation much easier particularly for removing the original exhaust system. The quality is first class and everything fits as it should leaving a professional factory fitted appearance to the vehicle. I used pot belly black paint on the portion that crosses the rear of the diff. I live in Australia so it had to be right first time. It is."

They had no problems, and their install price was reasonable. At first, I was somewhat disappointed in the system, as I expected the exhaust note to change dramaticallly, and it did not. However, after a rather lengthy (to me) burn in period, it did change. I was suprised at the time required for the system to "burn in". I did not make any long trips, and it took several shorter "in town" runs for the "burnt smell" to go away and the exhaust note to noticablly change. So far, I'm quite satisfied with the system."
Was this review helpful?Awesome!Posted on 01/21/12 Vlad B. - 2009 Toyota Corolla (Wallkill, NY)Appearance Ease of Installation Price/Value Quality "I keep seeing this Borla axle back exhaust for the 2009 and up Corolla. I wasn't sure if I wanted it, but after talking to some buddies I went and order it a few months later. I don't know why I waited so long... It looks and sounds awesome. It's not too loud but when you get on it you will hear the difference and feel the difference. I have 50,000 miles on my 09 Corolla and it just goes without feeling like something is holding the car back. Shipping took a little long, but wasn't terrible even though I live a few hours away from where it was ship from, but what can you do. Get it if you love your Corolla as much as I do. Great add on to the car!"

Eric M. - 1996 Subaru Outback (Plainfield, NJ)Appearance 
Ease of Installation Price/Value Quality "I purchased the Borla Catback Exhaust for my 2001 Subaru Outback Limited (2.5L AWD AT 4DR). According to the charts, it was supposed to be a direct fit catback. Unfortunately it was not. That is why for ease of instillation I gave 1 star. I had to go to a custom muffler shop to have the catback installed. After some cutting, bending, and new placement of hangers (every hanger was in the wrong spot) it finally went on. Everything else gets 5 stars. Appearance is amazing. 4" exhaust tip is very nice. Sound is a deep throaty sound, and not a tin can sound. Gains on the upper end can be felt. It looks superb. Price was $542. This was much less then I was quoted for a stock replacement catback from Midas. Even with the added charge of customization it was cheaper then the stock quote I got. Quality is great. Stainless steel, and guaranteed for 1,000,000 miles. You can't beat that! I'm quite happy with this catback system even with the headache of installation. If you're patient and can find a custom shop, then I recommend this exhaust for a Subaru Outback wagon. If you're looking for a direct fit, this isn't it. My grade: A- "

This exhaust is no louder than stock while my vehicle is idling but gives off a deep rumble when accelerating. There is a noticeable increase in accelerating power. "
