        Great value, wonderful sound

        I researched thoroughly for an exhaust for my V6 Mustang. I wanted a great deep-sounding exhaust that wasn't obnoxious. This was perfect. Great throaty sound, nice rumble. And not noticeable at low RPMs. At higher RPMs, the exhaust can be heard nicely. A small amount of drone inside the car, but nothing bad. I would highly recommend!

        Put this thing on my 2008 v6 and it sounds amazing!! Not too far off from a muffler delete if that is the sound you are looking for.

        Love it!!

        This exhaust sounds amazing. Not too loud, and definitely not too quiet! Love the sound of it, and gives your mustang a nice muscle sound.

        Sounds good

        It's definitely not as loud as a lot of people make it out to be. But it certainly sounds much better than the stock muffler. It's loud enough to sound good without being obnoxious and annoying. It's a great pick in my opinion.

        Best Exhaust for your V6

        This exhaust is the best for your V6. It looks and sounds amazing. People are coming by and asking if I have a V8 under the hood and I just smile. If you are thinking about buying the SLP Power-Flo, go ahead and do it. I wish I bought a long time ago.

      Is this louder and more aggressive then the Mac boom tube you guys offer

      • The Mac Boom Tube exhaust will be louder when compared to this exhaust.

      Hello, I have a 05 v6 mustang automatic and I want to make this car a bit louder than the stock I currently have. Will I need to also replace my stock CAI as well? If so if I purchase "SR Performance Black Cold Air Intake" will that be a good match and will it require a tune?

      • Replacing the factory CAI is not required, neither is a tune. For full potential offered by this item, a tune is suggested.

      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.

      Bought the SLP exhaust a couple of months ago and it has disconnected from the mid-pipe a couple of times to where I have to reinstall it, what might be the reason this is happening?

      • If the exhaust is coming loose or separating, either the clamps are stretched, misplaced, or under tightened.

      I am thinking about buying this for my 2006 Mustang but am worried about how loud this is. Youtube videos don't give any justice as to how loud an exhaust is. I drive to school at about 7 in the morning, is this going to annoy the neighbors or would I get by. I love the tone of it but I understand it's literally called loudmouth. 1 answer
