        Easy fit

        I wish these came with clamps. The fit was perfect but it was pain to have to reuse the stock clamps.

        5 2012 V6 - AllenR Installation Time: Afternoon

        Great growl for your buck

        These mufflers were packaged very solidly with two expanding foam packets for rigidity and two separate boxes in the main carton for the bubble-wrapped tips. Initial inspection showed superb weld quality all around. The hanger rods have plain ends, which makes installation and removal a cinch. I painted the mufflers with matte black VHT high temp paint to reduce any weld corrosion (though my Mustang never gets wet!) and to make them disappear under the car, when viewed from the rear. Once dry, the passenger side was a breeze to install and the tip could be centered perfectly in the rear bumper cut-out. An Allen bolt at 12 o'clock tightens the tip onto the muffler. The driver side install was more of an issue. The mid-pipe and support tie for the rear sway bar, plus the length of the rear muffler hanger rod hitting the spare wheel well, made inserting the inner muffler hanger rod very difficult. I removed the sway bar tie and forced the mid-pipe flange up out of the way with a pry bar and the hanger rod was then able to be inserted into the hanger rubber. The rest of the install was easy. These are about half the overall weight of the OEM mufflers. The idle sound is much lower than OEM, which is what I was after; a nice rumble. (I have BBK Short headers and a 73mm throttle body). While driving, coasting with a closed throttle results in very little extra interior noise compared with OEM. At full throttle, the engine and CAI dominate any additional exhaust noise. There is though a significant drone inside with part throttle (such as climbing a hill at 40 mph). Sounds like when you blow over an empty beer bottle. I intend to add some sound proofing in the trunk and under the rear seat to try and reduce that. I don't really know what the exterior sounds like as I'm driving! However, I have noticed more people looking as I drive-by ! :) For the price, ease of install and the deeper sound, I'm well pleased with this purchase From AM

        5 2014 V6 - Kory Installation Time: Afternoon

        Sounds great

        I would highly recommend picking up some new exhaust clamps, my only issue with installing was the fact that I had snapped the heads off the stock exhaust clamp bolts. Took me extra time trying to find proper bolts to fit the stock claps. but other than my mess ups. this exhaust sound amazing for the price. No droning sound on the highway or in town. Only starts to get loud around 2,000 rpm. perfect if you don't have lots of money to spend but still want a nice tone.

        5 2011 V6 - NDMustang Installation Time: Afternoon

        Sounds Great

        Sounds great, makes my V6 Mustang sound much sportier without sounding obnoxious. Relatively simple to install. Spent most of the install time trying to get the clamps on my old exhaust off. Works best if you have a friend or jack to hold the old pipes in place when you work the new alxle-back in place.

        Great sound

        Installed in about an hour. Adds great sound , a nice mellow rumble. Bought these as a birthday present for my son. His only complaint about his Mustang is its too quiet. When he started his car after the install, he was smiling ear to ear. Recommend this exhaust, it was worth the smile.

        Great Exhaust For The Money

        Mufflers fit well and are easy to install. When paired with headers h-pipe and resonators the tone is nice and deep.

      Are these legal in California? And if not which axle backs are?

      Do the tips just slide on or needs clamp? An will they fit my 2014 Ford Mustang V6?

      • These tips will clamp on.

      Does this exhaust come with the clamps to attach axle-back to cat-back section? or just the clamps to attach the tips?

      • The SR Performance Axle-Back Exhaust comes with the clamps used to connect the axle-back to the mid-pipe section of your vehicle.

      I assume these are fully welded. Is it acceptable to add a weep hole in the muffler for drainage to reduce internal corrosion after short trips? If so, where?

      It’s says pair do I need to order 2 of them ?

      • No this would be the full axle-back assembly.
