Description
V8 Look And Sound. If you're looking to give your V6 Pony the dual exhaust look and aggressive sound of a V8, look no further than the MAC Dual Exhaust Conversion Kit from AmericanMuscle.

No Cutting or Welding Required. Unlike other aftermarket V6 dual exhaust kits that require cutting and welding the stock mid-pipe, the MAC Performance Dual Exhaust Catback system simply bolts right up to the stock factory Y-pipe for a no hassle installation. Just bolt on and go!

High Quality Construction. Mandrel bent from durable 2.5" aluminized Steel tubing for strength and corrosion resistance, this MAC Performance Dual Catback features chambered mufflers with massive 3" diameter polished stainless steel tips for classic muscle car sound and looks.

Application. The MAC Performance Dual Exhaust Catback System is designed as a direct bolt-on to the existing factory Y-pipe on any 1999 to 2004 3.8L or 3.9L V6 Mustang for more power and a more aggressive sound.Technical Note: When buying a dual cat-back exhaust kit for your 1999-2004 V6 Mustang, you will need to select the "Exhaust Hanger Kit" from the drop down option menu above to properly install your new exhaust.

Technical Note: AmericanMuscle recommends changing to a 1999-2004 GT rear fascia so the tips fit properly.

Does the stock hanger kit plus the added kit work with the new exhaust? If I purchase the dual exhaust system and take off my stock pipes will I be able to use the stock hanger kit plus the new one for the exhaust? Or do I have to order two new pypes hanger kits

Does anyone know what the dimensions of the chambered mufflers are on this kit? I was going to buy this and then later down the line I was going to cut off the chambered mufflers and put on a pair of pypes m80 inline mufflers. The pypes m80s are 14" long. If I were to cut the chambered ones off, would the inline ones fit in its place?

  • I think you will find the mufflers to about the same length, and even if they were not, any muffler shop can make them work just fine.

    I really love this exhaust on my 2000 V6. The only other performance mod I have is the $70 cold air intake also from american muscle. These two parts REALLY shine together. The exhaust has a really deep aggressive start up and then comes back down to a modest growl as you idle. Accelerating at launch is also nice and loud but again, once you hit your cruising speed it really calms down. I love that it doesn't sound phony like a bottle rocket screaming down the road. VERY happy I invested in this exhaust! As everyone else says, buy the pypes hanger kit in the exhaust section of American Muscle. My mechanic said install was virtually impossible without the hanger kit.

    Loud Start up.

    ordered it on Monday and got it Wednesday morning, cant beat the shipping. this is probably the BEST dual exhaust for your v6, the start up is ridiculously loud and so is the revving. sounds great when your on the road and took about 45 minutes to install, but you NEED TO NEED TO NEED TO order the "Pypes exhaust hanger kit" otherwise you'll never be able to get the exhaust installed.

    Best Bolt On Exhaust on the Market for the Mustang 3.8 and 3.9

    Great addition to anyones V-6 Mustang. I didn't buy from AM as I got it shipped for $270 from another site, but either way the improvement this exhaust makes is very noticable. Once tuned and in combo with a CAI, it allows the car to have more low end kick especially but throughout the entire RPM range. Sounds its best with said CAI and tune but even without provides a deep rumble at idle and a very nice growl even at WOT. Sound under acceleration is quite noticable inside the car and outside it and even at freeway crusing speeds you can hear its low growl which is very nice (and feel it...the mufflers sit up and in under the body so there is a nice pleasant vibration from them under your feet at higher speeds). Make sure you purchase a hangar kit for this as you need the two rear hangars and an additional front hangar on the RIGHT side (but be aware that this MAC may have hangars that are too thick for the PYPES kit, see my review of that part regarding that). Installation is easy for any muffler shop and can be done by a DIY person though I would advise two people if you're not using a lift. Of course you are not going to get the sound or performance of an H pipe with this, but you also don't have to cut, weld or mod anything to use this...and you'll stay emission compliant. I would say if you want a nice throaty sound for your V-6, a bit more performance, something that looks really good and you don't have alot of cash, this is the best exhaust out there. If you shop around for the unit AND for the labor, you should be able to get this on your car for under $400-I did it for $350...well worth it.

    Best for the price

    First of all, I ordered this somewhere else but wanted to put my review here. The exhaust sounds amazing & looks great. Now I always have my windows rolled down because I love the sound. Especially when you start it now I am actually proud of my v6 now. I highly recommend this turns heads too. Oh and also I did this with jack stands so it is possible with them.

    Good Mod, Worth the Money!

    Likes: - Easy Install - Great Price for Quality Construction - Throaty Sound - Fits well under V6 bumper (Pypes hanger kit) Dislikes: - needs to have slip joint at muffler vice weld. This limits necessary tweaks to clear frame, drive shaft and control arms. Not a big deal but does limit perfect fit. See pics, about 1/2 inch low rt side

    MAC Y-Pipe Exhaust

    I didn't purchase this exhaust from AM as they've just started carrying it, but if you're looking for what I believe is the best sound throughout the entire band for a stock/slightly modified V6 then stop here, this IS what you're looking for! Be sure to pick up some new exhaust hangers while you're at it and install will be a breeze.

    Best recommended exhaust for the V6. I was very pleased with the sound. No rasp, just low growl. Didn't purchase from AM as i got it about a year ago. Very easy install, make sure you have GT hangers. Highly recommend!

    Great buy for the money

    If you're looking for a good upgrade to you V6 in this price range, don't even think twice about buying this. My car went from having virtually no sound to turning heads everywhere I go. The start up is loud and the sound emitted from stepping on the accelerator is a deep, aggressive rumble. Install time was about 40 minutes but that's because my uncle works at a Ford dealership so we put it up on a lift and had the best tools for the job. As stated in other reviews, you also have to buy the hanging kit but other than that this is a GREAT modification. I bought the SLP Loudmouth II mufflers to put on as well but have yet to get them welded on, I'm actually not even sure if I want to change the sound now..

    Love it!!

    Love the tone! It took me a while to choose between true duals or this and im happy with my choice! Best sound is around 2500 to 3000 rpms, and cruising at around 1300rpms. Great bang for the buck!

    awesome!

    bought from AM bone stock mustang v6 5 speed..couldnt decide from flows or this and so glad I choose this. This was so much cheaper and heck those tips stickin out the back looks so sick people already asked me if it was a gt and I just laughed.. But sounds great.. No ricey poop sounding exhaust.. Deep lower toned growl.. Sounds mean especially round 3000 rpms it's heaven..so many looks and heads turned it's insane.. Barely can even hear inside of car with windows down or up so it's quiet but 50 times louder outside it's great
