HOw do you like it? How does it sound? Any problems? I thinking about picking up the dual out behind the tire system.

 

Somebody has to have a set. I did some searching but the results too broad. Checked out 10 different threads.

 

Never even heard of it. Gotta link?

 

Very few here have them. They can be had cheap though. I think their mufflers are chambered similar to that of a flowmaster.

 

while he doesn't have a new body style, I believe PacmansprcrwXX has that brand of exhaust.

Just click on one of the options in the side menu

 

When it's chambered how does it sound or perform? I guess it's a noob question.

 

Never heard them on the F150, but for what it's worth, I had their catback on my 2003 Cobra. Loved the sound of it and always got compliments on how it sounded. Not the highest quality built exhaust system, but it fit pretty good and had the best sound in my opinion.

Well, from reading the post below from their site maybe their mufflers are straight through like a magnaflow. I prefer the sound of a magnaflow over a flowmaster, but that's a personal preference thing. It may be best to call MAC and find out for sure their design, chambered or straight through.

Here's a link to their catbacks.

Mac was the first exhaust I tried on my truck. All I can say is I drove it from the exhaust shop to home and remove the entire system within 5 minutes of getting home. It killed my power and sounded like crap. Love the macs on my Mustang though.

 

That bad huh??

 

Which one did you get? What did you replace it with? Sorry to hear that.

 

After another 4 systems, including flowmaster(sounded sweet but power killer), and magnaflows(sounded like crap in my opinion), my exhaust guy finally made a custom 4" system with a 4" x 18" aeroturbine. This is the sound I'm after and it's one of the only mufflers that works as advertised, more power and at least 3 mpg gain, but F/I vehicles respond differently than N/A when it comes to exhaust changes.

 

Oh I see why it didn't help with your power. F/I motors need plenty of exhaust. So the Mac exhaust will probably be good enough for my truck. I have no mods and don't plan on any huge changes, especially not a supercharger/blower/turbo etc.

 

I've got the Mac dual right side exit exhaust system on my truck. Excellent throttle response, nice aggressive sound on accel., mellow while at cruise. Minimal seat of the pants feel, but I've got the 4.6 too. I'd certainly recommend it!
