    4 Top Rated Questions

    Will these mufflers fit on the pypes turn duel off road exhaust system for the V6. I want these instead of the street-pro mufflers.

    • Yes, these are compatible with the Pypes exhaust. However, due to them being a universal fitment, you may need to make some modifications.

    I have SLP loud mouth catback on my 2002 GT. If I remove the resonators would these fit into the existing catback?

    • This muffler is designed to be universal as it can be used on multiple applications. Being this is not a direct replacement part, modifications will be required to install this properly on your exhaust.

    Will this muffler fit on my 2016 Mustang GT?

    • The Magnaflow Performance Series Oval Satin Muffler would require significant modification and custom work to install on a 2016, and may be too long for a 2016 Mustang, in addition to not having the necessary hangers. We recommend an axleback designed for the 2016 Mustang for a trouble free fitment.

    Is this the same muffler that is used in the Magnaflow Street axleback (11-14v6)?

    • Hi, This Magnaflow Performance Series Offset 4x9 Muffler is a universal fit muffler for 79-04 Mustangs except the 99-04 Cobras, The Magnaflow Street Axle-back Exhaust is a direct bolt on for 11-14 V6 Mustangs.

      Great sound! No drone!

      I once had flowmasters on my Fox, and though they sounded great, made an unbearable drone inside the car when driving at freeway speeds. These Magnaflows fixed all that. Plus they sound just as good (maybe better?) than my old flows!

      2001 5.4 DOHC Swapped Mustang Magnaflow

      I installed a set of dual Magnaflow mufflers on my 5.4 DOHC swapped 2001 GT. The previous mufflers were Flowmaster 40 series. The new Magnaflows fit and looked great! As far as sound they are quieter than the 40's but had a much deeper rumble, good sound while idling but a deep rumble when you get on it! They have much less of a drone on the highway than the 40's did. They looked great, workmanship was spot on. No complaints.

      Overwhelming sound at high RPM

      Sliwtched from flowmaster 40s to the magnaflow, and loved the sound crusing and idle, but when you get on it its just flat and loud.

      Fit Great and Sound Great

      These are some really high quality mufflers. Coming from Flowmaster's these certainly made my drive and the tone of my car much more enjoyable. The quieted down my ride, as well as the notorious flowmaster drone. Highly Recommend, they sound great.

      Great sound

      As much as I liked the sound of my Flowmaster mufflers, when I added off road cat-less X-pipes, the cabin noise and drone effect was absolutely awful and it gave one a headache while riding in the car at all. When I switched to these Magnaflow mufflers, the terrible droning noise in the cabin was replaced by the strong rumble that Magnaflow is known for. Well worth the change

      way better than flowmaster sound to me

      Well when I got car had factory x pipe with all cats remove and 40 flowmasters. It sounded good to some people. To me to loud and the drone inside of car was just to much. Lol getting older and wanted a better quality sound and lower tones from exhaust. Put the magnaflow catted x pipe in and then topped it of with these magnaflows from american muscle and couldn't be happier. So much smoother of a sound. Lower and just a very clean sounding exhaust. Not for the guys who want to have the loudest but if you want a good clean exhaust magnaflow is the way to go

      Best in the business

      Bought these to replace my old three chamber loud and obnoxious mufflers and i wish i would have sooner. It was so easy to order get my new mufflers and get them exactly when American Muscle said i would. Fit was perefect took a little longer than i thought to take the old mufflers off but overall not bad. The sound is incredible its much more tame sounding but at high rpm you can deffinately hear the roar of the engine come out. Gotta be the best mufflers out there I absolutely love them i recommend to any mustang owner for sure.

      Completely changed the sound of my car, has a nice deep tone to it. Not too quiet, but also not loud enough to wake up the neighbors. Great product overall.

      Good Sound But Quieter Than Expected

      I bought these mufflers because the other mufflers I had droned a lot on the highway. These mufflers definitely took away the drone that I was experiencing. It still has a good throaty growl when you rev it up, and when cruising around, but it is quite a bit quieter than I thought it would be. The install took 2 hangers, and about 4 pieces of extra tubing to get it fit in there. When I installed mine it required welding because of the catback system I have in place, and it took about 2 hours to do. If you want good sound with less drone on the highway, I would recommend these.
