        Great muffler!

        Very nice sound, little louder than expected but sounds great even on the v6, definitely would buy again !!! About 1.5 hr. Install, took longer to remove old muffler than installing new !

        Sounds Amazing!

        Easy to install, great sound on my 2005 Ford Mustang 4.0 V6, looks clean, much better than the stock exhaust. If your undecided about which exhaust you want, hands down you should buy this one.

        Amazing Sound for you V6

        The SLP Power-Flow provides the sound that I was looking for. Installation was very easy and the look is fantastic. The only criticism is that the front hanger needs slightly reshaped to avoid having the tip touch the bumper. I had to add spacers to the mounting bracket to keep the tip from touching.

        Great Upgrade

        Great sound and very clean look!, even when on idle the car has good volume and the noise definitely grabs a lot more attention when driving.

        Great sound

        Very easy installation, great sound to add to a V6. Nothing over the top and way better than stock. I found the fit good except the end piece rubs on the bumper and needs to stick out further. Maybe I just didn't install it quite perfectly. Otherwise it's amazing. Highly recommended mod.

      5 Top Rated Questions

      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.

      Helpful (5)

      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
