        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.

        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 (2)

        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

            Best rumble possible for a v6!

            This exhaust let’s more air flow coming out from the back causing a way louder deeper rumble, especially in the cold start or when accelerating.

            Good Sound and Easy Install

            Only took about an hour to install and the sound is worth the time and money it took. I just installed this exhaust two days ago, and have been asked if my mustang is a GT more in those two days than I have in the last two months. Extremely happy with this product.

            Sounds beautiful

            It really brings attitude and personality of a mustang, even a V6 mustang needs to run free and this is 1000x better than the stock.

            Nice and loud.

            Looks good and does whats its supposed to, make it loud! Note: there is a drone when your at like 2500 rpm, which is amplified for me because I have a soft top, but every decent exhaust will have that. Still love this exaust.

            Good as expected

            Very good noise, not too loud and def. not quite. I hear it little more than i want it in the car but its okay. it doesnt bother me. I would suggest it if you want a medium/high loudness

            Videos don’t do justice

            I was hesistant based off the videos, but after reading the reviews and testing it out myself it was very worth it. About 3 weeks later I’m still happier than ever with it. Trust me it’s a great exhaust

            Best Axle Back Exhaust for 05-09 V6

            Sounds just like you want it to, as close as you can get to a V8 with still hearing that V6 tone without it being overbearing. Best bang for your buck as far as quality, loudness, and overall performance gain with minimal to no drone!!! All under 250$!!!

            Probably the best axleback for the 4.0

            Everything arrived undamaged and ahead of schedule. Build quality is A . Install was super easy (make sure you adjust the position before you clamp everything down). Also, have a torch handy to get your old muffler off or in my case an angle grinder and channel grips to peel the pipe off. Sounds amazing when you step on it and manages to not have too much drone. Quite a deep tone that definitely borders on v8 sound.

            Nice sound

            Def sounds good no matter what anyone says only bad part is don’t expect a grumble or any popping when letting go of the gas( which I loved with my old Mustang). If you don’t like a lot of cabin noise then this isn’t for you but if you love to let people hear you then it’s perfect lol.

            Great exhaust but small drone

            The exhaust was great and instructions were pretty simple to follow! There us a slight drone inside the car, but if you can handle that, the car will sound mean and make your v6 roar!!!
