        True Dual for v6 I have an 03 v6. If I get the bbk shorty headers as well as the Pace Setter v6 dual exhaust adapter kit. and this mac catback. I should have everything and be ok?

        • The MAC Cat-Back Exhaust (96-04 GT, Mach 1) and the PaceSetter V6 Dual Exhaust Adapter Kit (99-04 V6) (Item #51063) are most certainly compatible. In fact, with that dual exhaust adapter, any GT catback will now work for your V6. On top of this, the dual exhaust adapter is designed to work with the stock manifold, and the BBK Ceramic Shorty Headers (99-04 V6) (Item #56099) is designed to work with the factory mid pipe; therefor these two products will work with each other!

        My 03 GT vert has a stock exhaust, should I spend the extra $$ for this setup or go with the cheaper Pypes violator or Pypes Pipe Bomb systems? Thanks in advance, John G.

        • This really depends on which sound you like better. If you like the sound of this Mac set up the best then I would go with this.

            Pretty decent

            Order came in quick. I had a local shop install it and there was a slight figment issue but it was easily fixed (left side was about half an inch too long). The sound from it is amazing and can’t wait to see what some long tunes and x pipe will do to it!

            Great Sound but you're better off getting the stainless steel version. The short pipe before the tips rusts out because water sits there. Otherwise they're great.

            Fantastic Catback - But Thing to Note

            This is the second time installing this catback exhaust. The first one was hacked up to install Super 44's. It was then rehacked to weld in a set of used Flowpaths so it was looking rough. That was 7 years ago. I repurchased this exhaust because I love the sound these mufflers create. They sound amazing with an O/R H and stock manifolds, but I have the new catback now paired up with BBK long tubes and a BBK O/R H which made the exhaust a lot louder. There is a few things to note: -Some people say these mufflers are too quiet - and they are at first. I don't know if heat cycles do it or carbon build up does it, but they will get louder over time. They are a cross between a Flowmaster and Magnaflow sound. Clean and crisp with a bass to it. I love the sound and the idle on these sound mean. -The clamps that come with this kit to fit on the tips are horrible. Plan on getting clamps similar to what the Magnaflow kit provides. On both kits I had to ditch the stock clamps because they are so cheap and flimsy that they break either under too much torque tightening or vibration over time. -The fit on this kit isn't the best. It will take some persuading to get it on right but when you do, it fits high and tight. Keep in mind I'm comparing this to Magnaflow and Borla Stinger catbacks I've had in the past so you can see the cost difference versus quality. All in all - I love the sound of these mufflers. The tips add a nice touch as when you look behind the rear tires the tips are long enough that you see a nice stainless steel tip. I posted a picture of my set up with the passenger side tip not installed yet from under the car. Give these babies some time to break in and you'll love the sound. They flow great as well for a chambered muffler. Do you homework on mufflers where guys did real life tests at the track and on dynos. This even outflows the standard Magnaflow muffler.

            classic mustang sound

            Only being able to afford a cat back at the moment this gives a great sound and volume as well as a very classic aggressive tone similar to a Flowmaster Amerian Thunder. Only complaints are lack of directions in the box which this isn't rocket science but I just wanted to confirm the flow tube angles. Another complaint is my exhaust tips didn't tighten up too well with supplied clamps and caused some rattling over bumps and the left completely loosened while driving. I corrected this with u-clamps from autozone. Overall satisfaction.

            decent

            this cat back is similar to flowmaster sounds a little different. I would not attempt to in still this on the ground it was difficult on the lift. I wish it was louder I do have it paired with an offroad x it is loud but not loud enough for me personally I do love the sound of the chambered mufflers.

            Not your everyday sounds the same exhaust.

            When I decided to change the catback on my 2000 Mustang GT I didn't want a Flowmaster exhaust again. I've had them before and although the do sound really good.....everybody has that exhaust. With the Mac Flowpath it's a much deeper throaty sound and won't be mistaken for any other exhaust. It actually makes the 4.6 sound like a bigger displacement engine is really the most amazing thing about it. Now on to fitment......I had a heck of a time getting everything lined up and fitted right to where it wasn't hitting anything, granted I do have a MM panhard bar on the car which complicated things but I still was able to get everything bolted on and clear of the chassis and rear suspension with the exception of the passenger side down pipe to tailpipe tip section, it's sitting against the plastic cover for the fuel tank (the exhaust doesn't get hot enough back there to damage anything). I'm going to put the car on a friends lift and weld in a section of pipe on both sides to get everything rear of the axle clear. As far as the factory muffler hangers are concerned the best solution to use them with the mufflers it to cut them in half and use the short section with one oem bolt on the inboard mounting clip to hang the mufflers, use Dawn dishwashing soap to slide the rubber hangers onto the muffler hangers. (dish soap doesn't destroy rubber, grease or oil will) Sound....cruising down the highway at 60 is quiet, you don't have to yell or crank up the radio, it's very nice. (still have the factory exhaust manifolds and H-pipe) Part throttle accelerating (and only accelerating) does produce a drone around 2000 rpm but with the aforementioned passenger side tailpipe sitting against the fuel tank I can't say it would still be loud at 2k once I have that fixed. Full throttle runs sound amazing, the car actually sounds angry. It's a unique sound that is completely worth the extended time it took to get everything fitted just right.

            Getting everything lined up can be challenging, but if you take your time it'll work out. It's one of my favorite exhaust sounds on a Mustang.

            Exhaust sounds great the tips took good, welds on the muffler don't look good, doesn't say mac on it anywhere. It honestly looks cheap, the pypes exhaust I had was better quality but it fits good and sounds amazing.

            MAC catback for 98 gt

            I love MAC, but I have to say this fit horrible. The sound is awesome deep and throaty. I paired this kit with a UPR off road X pipe on an automatic 98 gt. Sound is incredible and eliminates the rasp of the X which I don't mind. But the fitment is horrible. No real pics and its a pain in the butt with all the connections. If you buy this you'll love it , but you would be smart to do it with someone and with a lift. A lot of the clearances were super tight. The flow tubes are not welded in which makes that a pain . I think if MAC would weld the flow tubes to the mufflers that would make this a lot easier. My car has74xxx miles on it so its not super worn out underneath. Overall I like this kit, but the fitment could be better. THE SOUND IS AMAZING!!!

            I like the sound wish it was a little louder but it does sound good with o/r x pipe. I had fitment issues I has to shorten my x pipe 1.5 inch's to keep the tailpipes from hitting the differential if I had to do over I would buy slp or flow master the Mac has a lot of connections that are aggravating

            Sounds Amazing!

            I have an '01 v6. I paired this catback with the Mac o/r h pipe. It sounds just awesome on a sixxer! Very difficult exhaust to install and get aligned correctly. It hits the passenger side rear axel. It also hangs very low and my car is already lowered 2" on HandR ss. the clamps that come with it suck too. No matter how much you tighten the tips, you can still shake them side to side. I had to have them tack welded. Really not sure if I would reccommend this catback. It's almost like it's too long for my car or something. The hangers on the mufflers are stretched towards the back of the car too.

            Perfect Fit, Sound Awesome!!

            Bought this exhaust for my 1996 Cobra and it fit perfect. Install is simple and lots of adjustment with this kit to clear everything as needed. I was concerned with the tailpipes clearing my 315 rears but it was not an issue. Car is lowered and nothing hits anywhere. Sounds awesome connected to my O/R pipe. If your thinking of getting this exhaust go for it. Took about 2 hours to install.

            MAC Catback Exhaust

            I had this system fitted together with a set of BBK shorty headers, and a Pypes catted X pipe to my 2004 V6 convertible. The difference is incredible. It sounds great, looks great, and is much more lively. This is the way a V6 Mustang should sound! I definitely recommend using the Pypes exhaust hanger kit, and the 02 sensor extensions. These two parts greatly simplify the installation. I had a garage fit the parts, as I was unable to get my car high enough to do the job. With a hoist, a person could tackle this task, as all the parts were a good fit, and simply bolted right on

            Deep rumble, but not that loud

            Ok, Let me start by saying I've owned three mustangs, all with different exhausts(Ford Racing, Flowmaster and Pypes)so I know what a good set up is supposed to sound like. I had a shop install this one for me. These guys are good at what they do and they did a great job. They STILL had issues getting it fitted correctly. Some parts were loose, some were too tight. They had to spot-weld the tips in place so they wouldn't move on their own. After all that It cost me $200 for the install. That's not too bad. The sound is nice, very much a traditional Mustang voice.I have a factory H pipe and still have the cats in place. It's not as loud as the old Flowmaster 40's I replaced(one muffler had a hole in it) but it's richer, deeper and more noticeable at idle. More Bass and not as tinny as the Flo's. the sound has character in spades. The only thing I don't like is that it seems to amplify the sound of the mechanics in the engine. I swear I hear valves tapping when I stand behind the the tail pipes. (a crisp popping sound, almost like a crackle). I will say that if you're looking to cam your engine, this is the exhaust you want. It would sound amazing with a mild cam installed. There is little to no drone over 2500 RPM. I can actually hear passengers in the car now. The old flo's would drown out everything. the 3.5" pipes look tough hanging below the bumper. Very big and chunky. Much better than the old school 2" chrome straws I had before. I'm hoping the crackel will work it's self out over time and is just part of the break in. Maybe I'll just cam the engine and not worry about it. I was expecting more volume from this setup and that's kind of a let down. I'm thinking of adding long tube headers and maybe an off-road H pipe to get it louder. All in all it's a nice set up and a good value once you get past the fitment issues. I wanted a unique sound and that's what I got. Now I just need to make it louder!

            As soon as I got these exhaust installed and drove it down the road , I was smiling from ear to ear.
