I currently have a 2011 3.7L and am wanting to put an exhaust system on it. I have called local muffler shops and they can put on either a flow master 40/44 series or a magnaflow 14'' exhaust. Has anyone used either one of these on their 3.7 and does it sound good, worried about popping or backfiring occuring since its a 6 cylinder engine. If you have used it before does it sound the same as your last application on a v8 engine, obviously not as loud but still the classic flowmaster/magnaflow sound? I have also heard of people putting roush intakes on their 3.7L but am wondering how that sounds compared to an actual exhaust system like a flowmaster/ magnaflow.

I have a 3.7 in my truck and before I purchased the truck I was looking into exhaust systems as well. When I got my truck I was impressed with the sound it has for being stock, instead of getting a new muffler I cut back the factory exhaust pipe and put a 16inch long by 4inch wide chrome tip on the end. It now has an even nicer rumble and is decently loud when accelerating. It will never quite sound like a v8 no matter what you do but it can still sound pretty good. Theres a few videos on youtube of people with aftermarket mufflers on they're trucks with 3.7s but the videos dont do the exhaust sound justice.

The 3.7 doesn't get as much attention as it should. I would love to see/hear some of the high revving 3.7 exhausts.
