        will this fit my setup? I currently have the Magnaflow dualCat Back conversion system. I was hoping that buying this and short tube headers it will all bolt together. I don't want to do anything very crazy as far as custom pipes I like the bolt and go so I can return it to stock for any problems with emission problems. Where I live if you modify stock piping layouts they can fail you so bolt and go is the best solution for me. The magnaflow dual has been on for almost a year. Thanks for any help .

        • This will get you close to what you are looking for, but you might have to do some fitting to get the BBK system to mate with Magnaflow system when you get rid of the 2 into 1 connector pipe. The shorty headers should work with the BBK system with out any issues.

        I recently converted from a Y-pipe exhaust to this true dual exhaust and noticed reduced responsiveness. I also recently heard that allowing the exhaust gas to escape too rapidly could cause decreased backflow pressure which could burn out the valves. Is there any way of measuring the backflow pressure to determine if it remains within specs? Would a tune correct any problem with this?

        • Unfortunately there isn't a true formula to answer this question. Every Mustang reacts differently to modifications such as this, however what you are saying happened is definitely possible. Speaking with exhaust shops or tuners could help, however ultimately either adding more power or more restrictive piping is the answer.

        Is it California legal? And will it pass California smog regulations?

        • You will need to reach out directly to where you have your local emissions performed in order to verify.

            worst system ever

            Wow, what a piece of junk! What type of system comes with one side of duels? This had drivers to muffler and nothing for pass side. Cat pipes had to be bent to fit, hangers on cross pipe bent all out of shape. Another quality product from American Muscle. You got the last of my money, EVER!

            need a pipe!

            First off, please keep your stock exhaust mid-pipe. The BBK system comes with the cats, x-pipe, 1 mid-pipe, and 1 over axle pipe. The piping is for the driver's side. The passenger side pipe (already on your car) will be reused. Second, buy the hanger kit. It is $50 for two, and $80-$100 a piece at other shops in town. Third, you will need a GT axle back system. Pro tip- use a lift, or take it to a shop. The cats are in a tight spot, and removing them on jack stands was difficult without much room to work, and fighting rust as well. Sound is great, I paired it with the Flowmaster American Thunder axle back system. It brings a substantial increase in volume, and has a DRONE in the interior starting around 2000RPM -- she starts to roar around 3500. (For a daily driver, that might be an issue as phone calls in the car are hard to hear) The axle back I got was a "quieter" rumble, but she roars as is :)

            The dual exhaust kit arrived when I was told it would! Problem is, it was missing the x pipe and the template for the bumper valence. I am still waiting for their decision on returning the kit (what there was of it) and a refund a week later. The next box wants to know how long it took to install - 1 week so far!

            Sounds Great

            I ordered the BBK true Dual exhaust kit along with the BBK shorty tuned headers. Since we had a lift, it was a pretty easy install except for the coil pack bracket had to be cut to make the headers fit on the driver's side. I am using mufflers that came off of a GT/CS and the sound is great.

            Quality control needs work

            First one I received wouldn't even come close to fitting properly. The catted pipe in the passenger side was improperly curved and too short. AM sent a replacement and catted sections were bent properly this time but passenger side pipe was still over 2 inches short. Fortunately I had a different x-pipe to use and was able to make it work. For the cost I think BBK could do a better job!

            THE BBK True Dual Exhaust Conversion kits is a great purchase, excellent fit. It will be 3/4" short from the CATS end pipe to the X pipes. This is normal. the Coupler will correct the problem. Use a SUV or Truck jack stand this will help a great deal. Installation time will vary on the health and flexibility of installer.

            loud as heck

            I'll start with my particular setup. 2008 V6 manual, no CAI, stock headers, this product, and Pypes Violators axle backs (also sold through AM...i got the black ones and left a review there as well). If you are a daily driver you need to not make the same mistake as I did, and very carefully select your axle back. The violators created a drone over 100db loudness at highway speeds. I don't think they would have done that if the stock cats were still on. The setup sounded great on the city streets but once up to speed the drone was almost disorienting. I swapped axle back exhaust with a friend who had a stock '07 GT/CS. The GT stock mufflers are certainly a cut above the stock V6 sound but still pretty tame. Obviously doesn't sound as nice when accelerating compared to the Pypes but the drone on the highway is gone. So I'm sticking with GT axle backs for now until I am sure that something else will work with this setup and not cause hearing loss. I was told by the shop that the old midpipe was basically welded on to the headers, and that the install took some tweaking too. Axle backs aren't too hard to work with i replaced mine on the ground without a lift, but for the xpipe you might want to play it safe.

            I bought this kit and Borla Stingers axle back for my car. It sounds amazing, but not as nice as a V8 obviously. It took a mechanic about an hour and a half to install both of these parts.

            rough install, amazing product!

            Since I bought my mustang, dual exhaust has been something I've wanted to do and when the internals of my stock catalytic converters broke loose, I figured it was the perfect time to do it. The fact that this true dual system came with a pair of high flow cats made it perfect for my situation since my stock ones needed to be replaced. I planned on doing the entire install in my driveway but rusted bolts between the cats and the manifolds caused too much trouble so I took it to a shop. They did it quickly and fairly cheap too so I would recommend taking it to a shop for the install unless you have a torch to get the manifold bolts red hot to remove them and are able to get that torch around the egr tube and past the heat shields. Other than that this product fits flawlessly and sounds even better. I went with Pypes pyle bomb axle backs and the sound compared to stock is extremely loud. I always get looks and compliments from gt drivers. People even ask if its a v8 it sounds so good! Overall I recommend this product to anyone who wants to really open up the sound of your v6

            !!!amazingLLL

            I have to say, I was a intimidated at first to install the system myself. One mistake I made was I decided to remove the system one week before the new system arrived. Unfortunately I couldn't get one of the exhaust pipes off. So i cut it off and when I got the new system it required that pipe and I had to take it to a muffler shop to have it re welded. luckily it only cost me $25 so it was a very inexpensive mistake. Overall I think it's a great system it was easy to install and it sounds amazing.I paired it with the flowmaster Outlaw exhaust and it even sounds better than my wife's GT.

            Great sound, easy install

            Again installed on 08 4.0 with Xcharger. No issues with clearance, they send 5 clamps, so no need to worry about your rusted old one. Fit was good, bolts right in with no issues, though the O2 sensors are a pain. I installed them before the instructions said to, because it makes sense to tighten them off the car when you can work easily. Tough to do on your back but definitely possible. I paired them up with the shorty headers and some GT take-off's and they sound great. Makes my mustang sound as mean as she is.

            Love it, great sound, great price.

            I had this kit installed on my 2005 V6. I originally needed a new y-pipe and cats. The OEM Ford parts would have cost $1,400. On top of that, my original passenger side exhaust pipe had been cut and modified by the previous owner, so I chose to redo my entire exhaust system from my headers to my exhaust tips instead. I paired this kit with: BBK Ceramic Tuned Length Shorty Headers (05-10 V6) Item #56100 Pypes Mid-Muffler Catback Exhaust Kit (05-10 GT) Item #20019 GT500/CS Rear Bumper Cover w/ Diffuser - Unpainted (05-09 All) Item #53674. Don't forget to buy the SR Performance Stainless Steel Exhaust Hanger Kit (05-10 All) Item #20021 for the driver side exhaust. You're V6 does NOT have these hangers. I didn't use the exhaust pipe from this kit because I installed the Pypes catback kit, but the pipe would have been a perfect fit. NOTE: This kit is designed for an axleback exhaust kit. I went with a catback exhaust kit for two reasons. 1) I needed a second exhaust pipe to replace the old, modified passenger side exhaust pipe. This kit comes with ONLY one exhaust pipe for the driver side. It is designed to reuse the original passenger side exhaust pipe. The OEM Ford pipe was priced at roughly $120. This made purchasing a catback exhaust kit about the same price as an axleback kit. 2) I specifically wanted the Pypes M-80 Bullet mid-mufflers. They are one of the only aftermarket mufflers for a V6 that, in my opinion, sound good at all times. They do not have a loud drone on the interstate that is sometimes heard from other kits like the Flowmaster American Thunder mufflers. These mufflers have a deeper tone and they are much throatier sounding. At the same time, they are louder, but not too loud. And, they are significantly cheaper than most other kits, but they yield great results and are of excellent quality. Overall, the shop only asked for $300 to test fit, paint, and install the new rear bumper, and they asked for $500 to install my new headers, cats, x-pipe, exhaust hangers, and catback exhaust. Had I only installed this kit, the shop had priced it at a maximum of $100. The $500 was for only installing the headers, but they said they would just install everything for that price as a packaged deal. The shop said all of the parts fit perfectly and installed easily. American Muscle had everything delivered to me quickly, and all of the packaging was superb. There was no doubt that all items would be undamaged and in perfect shape due to the generous amount of packaging material used inside of the shipping boxes. The new cats are great. They are high flow and allow much more exhaust flow compared to the original cats. This paired with all of the other mentioned parts has really opened up the sound of my V6. People have already been complimenting my new sound, and I often see people look at my car as soon as the exhaust revs up. There have been several times when people have asked if I have a GT. If you buy this kit and pair it with the right parts, you will not be disappointed. Take your time, research all of your parts, listen to V6 audio clips, and make sure to ask lots of questions. Once you make your decision and get your parts installed, you will have a huge smile on your face every time you fire up your Mustang.

            Great X-Pipe Upgrade !

            This X pipe is amazing! So much better than the stock exhaust flow its incredible. The X sound lets you hear that raspy tone when you punch it. I installed this myself and have 2 tips. 1 - Do yourself a favour and get the hanger kit with it 2 - Install the whole system before tightening down all the clamps. This will allow you to adjust the system and keep it level, if you tighten all the clamps as you go, by the axleback you will be compensating your angle and may cause you to have rub down by the pumpkin and control arms. The cats are great upgrade in this kit instead of the restrictive ones you have right now. Definitely recommend this product !
