Installed Magnaflow Exhaust on my 2011 Jeep Compass

So it turns out that the Magnaflow Jeep Compass 4x4 exhaust that fits 2007-2010 models (Part #16777 Magnaflow Exhaust #16777) WILL fit on the 2011 4x4 Compass!!! Yet Magnaflow states that 2011 needs to make a new custom exhaust to fit the 2011s. How do i know it will fit? Because i installed it last night! Took about two hours but i got it done.

I still had the old stock exhaust off of my 2008 compass and compared it to the stock 2011 exhaust. They look exactly the same but the 2011s had an increase in diameter from 2.25" to 2.5" and about 1 foot long on one section of it (No its not a catalytic converter). And they painted the muffler black on the 2011 models.


I'll post numbers on any increased MPG next week and i'll post sound clips this weekend.

Here are the photos:

The stock exhaust bu bye you heavy beast you!

Edit:
Sound clip
Warning:This clip makes the car sound SO much LOUDER than it really is. You BARELY hear it inside the car.

Please see if you get a chance to upload a video sometime of how it sounds. What do you think of the sound though thus far?? I have a 2011 Patriot but still looking for some good exhaust options.

Props to you! I really need to do the K&N + this exhaust before I start driving it in the winter.

Does it feel any quicker/more responsive? I listened to your video of the exhaust on your 08..can't see any reason it would sound different.

Its very difficult to feel any difference with the CTV transmission on lower speeds. On the highway it definitely feels alot smoother. Acceleration feels better but its nothing earth shattering. Again, i do this more for the improvement of MPGs.

True it doesn't sound too different. The only difference between the too cars was the old one was a manual and the new one is an auto.

K&N what? Just a filter, or the FIPK? If it's just the filter, don't bother. K&N just has a great marketing dept, there's no benefit to that product. If you want a reuseable filter, go with Amsoil. No oiling involved with that one, and it filters better.

I hadn't really decided, but the FIPK is cheap enough where I'd probably try that. Basically the same setup w4rh4wk has tried would be nice.

Why won't they fit Patriots ?

Perhaps the 4x2 and 4x4 exhaust systems are different ?
