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.

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.

  • 5 to 8 HP depending on your modifications. It will be louder then your stock muffler and allow more exhaust gas to exit faster and you'll notice a difference. However If your looking for more horsepower and torque and plan for future modifications i.e.: CAI & Tuner, headers. You'll benefit more from adding a true dual exhaust system such as a Ford Racing True Dual Exhaust (05-09 V6).

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.

    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!!!

    Great muffler....just one mini problem.

    November 10, 2012

    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

    April 20, 2012

    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.
