    Do you sell one for driver side? I wanna order this mod for now but I would like to convert to Dual later on. Just wondering if you guys sell one for the driver side.


    • Unfortunately, we only sell the Power-Flo for the passenger single exhaust. I'd suggest contacting SLP directly to see what they might be able to do for you regarding a driver's side pipe when you convert to duals.

    do i need the exhaust hangers for my 2010 v6 or can i install it without them?


    • New exhaust hangers are not required for the SLP Power-Flo Axle-Back Exhaust, unless your current hangers are worn or broken.

    Just ordered the exhaust and payed for next day shipping. Very stoked to see how this goes. I am curious opposed to its performance. Because it's a straight through pipe, will there be any increase in hp?


    • While there will be a slight decrease in back-pressure, axle-backs exhaust are not tested for performance gains as they are mainly used for sound purposes. This will still help the vehicle flow better, but the gains will be minimal when compared to a cat-back exhaust unit.

    Is this product 50 state emission legal ?


    • Yes, as this product does not change the amount of emissions the vehicle is making it is legal in all 50 states.

    do you need to get a hanger kit for it? I have a 2006 and i want one but dont want to spend the extra money if i don't have to.


    • If you are just purchasing this SLP Power-Flo Axle-Back Exhaust (05-10 V6) you will not need to purchase the hanger kit.The SR Performance Stainless Steel Exhaust Hanger Kit (05-10 All) just helps to get a cleaner installation and help keep your exhaust tip aligned in your bumper cut out.

      don't believe what you read

      i have a 2010 mustang, i got the axle back as well as the kit to put it on and had it professionally installed. i am embarrassed to drive my car. im going to have this euro-sounding trash taken off and sell it. it sounds nothing like a mustang should. i advise not to buy this product for a mustang, it suits umm.. maybe a honda

      I am in love with this exhaust. It makes my 09 v6 sound like a monster. It roars at takeoff and yet sounds great at idle. I love it. Recomended for any v6 owner!

      Kick ass!!

      I had a flowmaster on my 2007 4.0 and it was loud and it had great performance, but it sounded more like a tuner. I bought this product at a great price and I can feel a major difference in the power. It has more of an aggressive, mean sound to it. Super great!! It took maybe twenty minutes to install.

      Awesome exhaust

      This SLP axel-back exhaust absolutely blew me away. The start up, idle, take off, and cruising tones all sound awesome. Aggressive V8 Sound was very right! Did the install myself no problem. I recommend this to any V6 owner

      I was definately not expecting this exhaust to sound as nice as it does. When i first started my stang after a quick installation, i had a big smile. Not only is this exhaust loud, but it sounds great. My friend has an infiniti g35 and now my car sounds better and louder than his. I definately did not expect this much from an inexpensive axle-back exhaust!!!

      Looks great well made

      the only thing I found is the muffler pipe that clamps to the exsi sting stock pipe is a little to big in dia. so I needed to shim to fit .because when I tightened the clamp all the way it still was loose. besides that it fit good tone of the sound sometimes seems to high pitch rather then a throaty tone. john 2010 mustang

      LOVE IT!!

      As a high school student, we all want to outdo our friends to see who can have the coolest cars and what not. So after months of consideration, I recently purchased this and had it shop installed. My stock exhaust was welded on from the last owner for some reason. But I absolutely love the sound and look of this on my 2009 V6 Mustang! It has a noticeably louder, deeper idle sound and when you really gun it, that's when you notice the biggest difference. This'll make your V6 roar. I've asked all of my friends for their input and they say they love it and it sounds "sexy!" I STRONGLY recommend this for any owner looking to beef up their V6's sound!

      Great muffler....just one mini problem.

      Well. I recently bought this for my 2010 V6 to give it a better sound due to the stock muffler is restrictive to all ends of the earth because it wouldn't roar at 5K, it would hiss. So I got this to make it roar. And it does. But here is a tip 2010 owners!! It doesn't fit out the back due to the rear end so your gonna need to go buy a 2.5"-2.5" exhaust exstension and another 2.5" exhaust clamp due to it doesn't reach the back of the car, and this way your exhaust tip can stick out. But...if you REALLY want loud sound, don't put the tip on run it. It sounds BEAST. It was louder than my friends dual exhaust Pontiac GTO, and I mean LOUD. I was getting such a rumble I could hear it from 1.5k rpm thru the whole rpm band inside the car! So this is super loud being the fact it practically a strait pipe so I TOTALLY reccomnd this to anyone who wants some actually growl and roar to there V6

      SLP Power-Flo sounds good

      Very satisfied overall. Had to put a 4 inch extension(about $4) on between the muffler and chrome tip to get a satisfactory fit on my 2010 Mustang.

      Excellent Choice

      I'm absolutely amazed at the sound quality and product finish. If your looking for new axle-back look no further. I researched all the axle backs and finally decided on the SLP Power Flo. 6 months of comparing Flowmasters, Magnaflows, Pypes and SLP led me to here. The videos on YouTube don't do the power flo justice. Looking forward to more purchase from AM now. It's also relatively easy to install yourself.

      SLP Power Flo

      OMG she screams now! WAY louder than the silly dual exhaust charger sitting across the street. THIS EXHAUST IS BEAST. After a few weeks maybe a month of digging and listening to sound clips I decided on this and i am WAY more than happy with my decision! Way to go AM for another great and amazing product. The shipping was fast as well and I was pretty surprised and the amazing job they did packing the thing. Thanks again -Mustang_Blackwidow

      Recommend with some reservation

      I had a Pypes muffler on the vehicle and was looking for a little louder sound. The SLP was easy to install but it sounds nearly identical to the Pypes. I am a bit disappointed. Installation took about 45 minutes.

      Makes a great sound for a v6 but

      Makes your v6 sound like a beast but the loudness gets irritating me after a while. Makes a great idle sound and sounds amazing when your accelerating if you want to make a lot of noise. Though its a cool product I will not keep it installed on my car.
