5Great sound
By Brian J. Weber
I put this on a 2007 Subaru Forester X and it works wonderfully. Deep sound and low back pressure. Great design the balances volume and performance. Pretty small too so it was easy to fit in with a nice long tip. It is a straight through design so in between shifts and a deaccel there is some rumble that sounds pretty cool.

5Fantastic!
By T. Shaukat
I have to say that this is a GREAT buy. My mechanic wanted to order me a Magnaflow which cost $290 for the muffler alone, through him. This Borla performance muffler is just awesome, it's not just the incredible price tag, its what you get for your hard earned money!The sound Borla creates, at least on my BMW 323is e36, is very stunning. Heads turn when I drive by and any car enthusiast's curiosity is sparked when I'm around the block. I'm not kidding, this thing is LOUD.With the inline 6 I have the exhaust system straight piped from the cat with 3" piping, to the muffler with a nice custom Tip, resonator deleted. The sound is really manageable, if I don't feel like riding too loud I simply decrease how much I gas it. But when you are going this thing gets LOUD.Coupled with the BMW engine its a very raw, smooth sound. No high pitched Rice Rocket crap here, the car idles with a purrr like noise that is just awesome, Things like downshifting and rev matching just sound awesome, if I simply gas it in first or second gear with the clutch out, then stop gassing and let the engine decelerate, it creates a loud droning that alerts you of a great exhaust's presence. It pops and crackles like a tuned race car does.In the lower gears it sounds just raw, like pure engine with a borla flavor. When under 4k RPMS I feel a little shaking from underneath the car that resonates up to my cabin. If I have the rear gill windows open then sometimes they rattle, but otherwise there is nothing making noise besides the radio and the exhaust. In the higher RPMS this thing only gets louder, and past 4k I feel an extra "oomph" factor.This is a wonderful buy, its a universal exhaust and is very lightweight, as is all the stainless steel piping. (The original piping and muffler were SO rusty and incredibly heavy! It took 3 people to hold on to the muffler as we took it off, but my mechanic held the new Borla in one hand with ease!)I highly recommend Borla, this is by no means a cheap muffler, you get your performance and it sounds amazing! I have recommended it to a couple of friends, one friend in a Mazda Speed 3 and another in an STi. Both sound incredible, not quite like mine but the boxer engine and whatever the hell Mazda uses both also sound raw and smooth, I hate raspy exhausts, high pitched ones, etc. This gives you neither. Highly recommended!I instantly sensed a better throttle response in my car, and in the higher RPM's it seemed to pick up a little more quickly. Gas mileage is also just a bit better.
