I don't know about the 4.7 but the Magnaflow cat-back sounds great on the HEMI.

I was hoping it would sound as good as my old 5.2 GC with a gibson cat back...

The Magna Flow Cat Back is the same for the 5.7 as it is for the 4.7, all the hangars were in the right place also, hell my box even said for "5.7l Jeep Commander ONLY"

I always had Magnaflow since I wanted something quiet but for a change I want to switch over to something which is not too loud but has high HP. Any idea on Flowmaster?

I put a Flowmaster 40 and K&N CAI on my 2000 CLK 430. The sound was great (not too loud). When I sold the car the guys at the Mercedes dealership loved the sound. I could feel a difference in power at the low end which was what I was wanted. I just ordered a K&N 57 CAI and Magnaflow cat back for my 2007 Hemi Commander Limited. I plan to install next week and I'll post results after I run the new system. Anyone out there have similar? Let me know what you think. The only question I have is about the resonator. Should I keep it or lose it?

Did you upgrade your exhaust?

I had a local shop weld in a Magna flow muffler. I kept the stock resonator and pipe. It sounds really good.

So, what would sound better for the 3.7L wuss? I like it quiet on idle and cruising speed but, wouldn't mind a little growl when I put the pedal down. Any suggestions (besides upgrading to the Hemi)?

I decided to try something different. What's the worst thing that could happen? I chop it off and try something else. I went with the new Cherrybomb Vortex muffler. I just went with 3" all the way out with a stainless tip. It is very quiet below 2000 rpm's but stupid loud above 4000 rpm's. The best part of it is the lovely crackling noise when you manually downshift during deceleration. It can be a little droning on a road trip though. I wouldn't recommend it if you do a lot of highway driving.

Here is a link:

By the way, this is my first post and I haven't add all my information yet. It is on an '06 Hemi Limited QDII.

I havent voted, yet, but I used to have a Flomaster 50 series in my 04 F150 5.4L. It was decent, but for some reason sounded butter on my 99 F150 V6 (??). I have heard good things about the Magnaflow...

Will have installed, will vote
