        Great kit

        Great kit, only had a problem with the exhaust hitting the driveshaft while hanging in the carlift and the rearend was hanging down, but on four wheels on the ground no probleem enough space between the shaft, exhaust and catback. Further one tip hangs a litle lower than the other one. But the sounds make everthing allright. Its amazing and tunnels are even more fun. Make sure the kit is complete because you need to cut the old exhaust in half to remove it, or get the reaxle apart. Not bought at american muslce but same kit, shipping from america was the same price as the exhaust. Bought the kit in holland

        exhaust installation

        i watched the video prior to receiving the exhaust system and when it came it took me less than 1.5 hrs to remove and replace the cat back system. I was very impressed with the style and fitment right out of the box. I would suggest this product to everyone

        Sounds aight

        Alright I had a custom exhaust before this and yeah this sounds nice and deep but it’s not loud and crazy, I have a v6. It’s not much of a difference from what I had before but yeah it’s ok . Loudness scale would be 5/10 it’ sounds aggressive but it’s not crazy

        Happy with it overall. I recommend not having it welded until you break it in. Had some issues with how they fit. Took it back to the shop 3 times. Still getting a knocking over bumps. Pipes are also bent differently. Overall it sounds good, definitely not loud but good rumble. I wanted quality muscle car growl over high raspy notes. Looks nice too. Everyone likes it.

        Fit perfect and great sound

        The kit came with everything needed and bolted up perfectly with the factory mount locations. Gives a aggressive V8 sound from a V6 and looks great. Took about 2 hours to install.

        5 1999 V6 - JamesH Installation Time: Afternoon

        Nice exhaust

        System sounds really great. Much better rumble than my stock exhaust. The hardware being included was a major plus to this system and made it easy to install. Not on American Muscle, but the packing could be done a bit better. Nothing was damaged, but there was very little protective padding keeping the pipe sections from clanging against each other. The mufflers and the Tips were well protected however. The instructional video didn't point out installing the set-screws into the tips to secure them to the hanger. I think that may be were some peoples 'clanging' sounds are, if they didn't catch that.

        Awesome sound, nice and loud rumble. Way better than stock. I have basic mechanical experience and it was pretty easy install. I did not have a lift so I had to take off the tires and shocks to get it over the axle. That was the hardest part. Everything fit and lined up perfectly.

      Is this kit legal for street use in California?

      • This exhaust is legal for street use in California.

      I would love this kit with black tips for the 2000 v6, is it optional because I notice these tips have the hanger tube affixed to the tip so I can't just purchase black tips.

      Can the mufflers be cut off and replaced with like say a shotgun muffler or straight piped?

      Will this work with the Magnaflow Direct-Fit HM Grade Catted Y-Pipe (99-04 V6) Item 402876 instead of the stock mid pipe on the 2000 v6 Mustang?

      I have the exhaust installed with all bolts tightened, however when idling with A/C on or sometimes without A/C on I’m experiencing an exhaust rattle. What can be causing that issue?

      • This could be something blocking the insides of the exhaust itself, or an issue with the alignment and installation of the exhaust itself. We would advise that you should have a local service professional take a direct look into this as we would be unable to diagnose the issue without physically inspecting your vehicle.
