  Nice product

  I should have bought this system before I bought the Pypes pipe bombs. This Flowmaster system is just what a v6 should have on it. It will NEVER sound like a v8 but it adds a little more sound without sounding like a rice burner.

  Costs a bit more but worth it

  My car is the one that appears in AM's install video for this product. I've been driving it for a few weeks now. The fit is very good and quality of components seems top notch. The sound is more of a low rumble that builds to a growl. The external sound clips in the video are accurate. The interior sound is definitely louder than stock. For the most part it is pleasant but you will have some drone cruising on the highway under load from about 2000-2500 rpms. This is probably inescapable with any 'true dual' system that doesn't have Ford OEM mufflers. It appears to mimic the GT exhaust so if the drone gets to you some stock GT mufflers would probably bolt right on. That one small gripe aside I am very pleased with it and do believe it is worth the extra cost over the cheaper options.

  Great product!

  Everything fit great, clamps all fit didn't need to weld. Sounds great. 100 times better than stock at startup, rev, idle, and while driving. Not obnixous, just loud enough.

  Brought a smile to my face

  I was lost looking at different exhausts for my car. I knew i wanted duels but had no idea what to get. I listened to clips on youtube but that only helps so much because you still dont really get the full effect. I settled on the flowmasters. Shipping was fast. Everything got here in one piece. It cost under $200 to get it installed. The chrome tips out the back look very nice. The garage that installed it said it took alittle time getting them installed right but they finally got it. When i fired it up i knew i made the right choice as i turned and looked at my kid and realized we both had a huge smile on our faces. I am very happy. Thanks AM

  Flowmaster review

  The Flowmaster exhaust was a fairly straightforward install. The exhaust sounds great. I get better gas mileage, better airflow, and have a smoothie and cooler running engine. Had to bend the pipe down because they were not welded completely strange but otherwise the Flowmaster exhaust true dual cat system is amazing. Thank you American Muscle

  Great System

  Mustang is an 08 V6 I had the GT rear bumper cover installed I next ordered the FlowMaster Force II system and took it to my exhaust guys and they installed it for $100.00 plus tax I highly recommend using a shop it went so smooth arrived at 8am and by 9:30am it was done and welded. The system has a great low idle note and normal driving is mellow through the back seats but when you get on it, it screams with a throaty deep 6er note. The install looks great and fits nicely up under the car does not look out of place at all, all the hardware worked as the instructions say and moving the mount is a breeze no need to tap the holes for even the OEM bolts are thread cutters put a bit of oil on the threads and run them up. I also disconnected the battery so the computer would be reset and in learn mode to adjust faster to the new freer flowing exhaust pressures and readings at the O2's. Highly recommended system.

  Excellent Exhaust for your V6 Mustang!

  I should have done this a long time ago. It makes sound so much better. Especially around 3,000-4,000 RPM just opens her up. As for a bit more HP, probably some but not very noticeable however I wanted it more for the sound and it does deliver but it isn't too loud to attract "unwanted" attention for those who know what I'm talking about.

  Great sound for a sixer

  Fit-wise, this product was a BEAR to install, had to wait for a second set of hands to coerce it to go in. But it IS possible with little more than a couple jack stands and a jack. The instructions tell you to cut AND grind the supports for the factory y-pipe off, but I didn't want to risk an exhaust leak and it would have required dropping the exhaust at the cats. So instead we cut a couple inches off the BACK of the Scavenger X-pipe and everything fit after that. The over-axle pipes are tricky to get in place, your rear end needs to be WAY in the air with the axle hanging so you have clearance. Recommend a lift, but it's possible to do without one. The first fire up was so worth it! It sounds beefy at startup for a six-cylinder then quiets down after it warms up. I've got stock gears (3.31 rear gear) and it starts to drone at about 85 (80 on the perf tune) but it's got a nice sound!

  Great rumble behind a 4 liter !

  Sounds fairly loud with a good rumble but not obnoxious to have you crazy. Inside cabin volume went up a little but it sounds amazing ! Great mod and a must have !

  Sounds awesome!!!!

  I bought this exhaust for my mustang and it sounds awesome. It took about 4 1/2 hrs to install. The only negative thing I have to say about this kit is the fitment sucks. The pipes were too long so we ended up cutting a good inch off the flow master. We dropped the suspension to get the rest of it in. I would definitely weld this kit. We used the clamps, but found out one of them was not keeping tight which made the muffler hang low. 2 screws fixed that but I will be getting it welded soon.

  Great Sounding System

  I have always been a fan of Flowmaster. This is a great sounding exhaust during acceleration, at idle it has a nice low rumble but doesn’t have that loud droning at highway speeds. My car was recently struck in the back and I decided to have the body shop install the Flowmaster exhaust over re-installing the Pypes system that was on it before. Came out looking very nice, fit well, especially with the GT bumper cover I had them install. I personally like the Flowmaster a lot better that the Pypes system I had on it before, deep rumble but without being obnoxious. If you like it really loud I wouldn’t recommend this for you. I would usually install this myself but since it was in for bodywork I had them do it while the car was apart. I can only tell you what the shop told me as far as the install, “it was a royal pain to install and took me 3 to 4 hours with a couple guys helping out, but it sounds really nice”. He ended up welding it instead of using the clamps and he dropped the driveshaft and lowered the axle to get it in. Overall I’m very happy with the Flowmaster system, would definitely choose it again.

  Love the sound!!!

  For most people. they want a full on V8 sound with their Sixxer. If you want that, don't buy this exhaust. It makes the 4.0 sound like a very nice V6, with a nice rumble at idle and then brings out the European sound of the V6 when you get on it. For those worried about breaking the 95 dB law in certain states or overseas, this one sits right at 93.2 dB for sound, so it's loud enough to notice, but not loud enough to get a ticket! As for installation, it says direct fit, also says to cut off 12" off the stock exhaust I believe (Put it on over 2 years ago, can't remember exactly), you have to cut more. I would recommend taking it to a shop, it took my wife and I around 6 hours to get it installed correctly (comes with clamps, I welded it instead) and its not the first exhaust job I've done. A pain to put on, but worth it, and the 3" polished tips are nice. Overall, I love it, and will definitely buy Flowmasters again, I would recommend getting it powder coated to keep the rust away, which I will do next time.
