Flowmaster on a 4.0

Anyone put a 40 series Flowmaster on a 4.0? If so, how does it sound? I had one on my Ram 5.2 and I loved the sound, just curious what it'd sound like on a "buzzin' half dozen!"

well my cherry bomb amplifies the lows and mids pretty big on the 4.0. I guess it sounds a little more like the rice burners but with that specific jeep I6 motor sound to it, compared to the deep, throaty rumble that the cherry bombs typically have on the v8's. I can imagine the same would pass over across the board somewhat evenly.. Not sure if that answered your question since it's a diff muffler but there's my $.02

Sound was good. On my application, the inlet weld broke so i had it patched and braced. then 6 months later the baffles inside went and it rattled and sounded way too loud(lasted 2 years total). I went back to Gibson which lasted around 6 years the first time around. Its still loud, but to me its a cleaner or more refined sound. My 2 cents

Not sure what series is on my 4.0 as it was on before ownership but compared to the Cherry bomb on my previous 4.0 it sounds stock to me. If I really get on it maybe it has a tone to it? I'm pretty sure there's even a header on this one too lol..

On my 93 ZJ 4.0 it has a flowmaster with no cat and it sounds pretty good! No drone inside either unless you're putting around town at 1500 then it gets annoying

I agree with camaro^, I like the sound I get outta mine. But you're not gonna rumble the car next to you at the stoplight or anything.

I've got a Super 44 welded onto my '98 4.0 and I love the sound. I've had it on now for 2 years or so and its held up nicely!

Hope it helps!
