Just wondering about aftermarket exhaust options for the 3.7. Also, if anyone has changed the exhaust, any noticeable performance gains?
I like how the stock exhaust sounds but wouldn't mind a little more rumble as long as it doesn't drone.
I'm currently running a Magnaflow resonator in front of a Flowmaster super 44 si/so. I like it because there isn't any drone and it has a deep tone to it without the harsh raspy noise in the higher rpm.
2013 3.7 supercab here. I have a true dual system I had done custom. It has two 2x2 free flow mufflers that are inline. No drone with the two mufflers, but there was when I only had one. Sounds mellow and throaty. As close to a V-8 as a V-6 will probably get.
Currently I'm running a Flowmaster Original 40 series SIDO. It sounds pretty good. Deep at low RPMs, raspy at 3000, then at 4000 and above it screams like a race car. Probably going to true dual Super 44's with an H pipe in a few days to deepen the sound a bit. Not a V8, but seems to like aftermarket exhaust more than the older V6 F150s and rangers.
In terms of performance, it feels a bit quicker. Not by much, but a little bit.
I have a resonator delete on my 3.5 Cyclone. It sounds the same as stock at WOT, but has a deeper tone at lower RPMs. There's a very slight amount of drone around 2800 RPM, but it doesn't bother me.
