Trouble choosing muffler/exhuast system

[Cadon69]

Drone was one if the main reasons I didn't go with flow master. Also to me the magnaflows just don't sound as deep gut grumbly as I wanted from my truck. That's why I went with a spinTech. I don't have any drone at all that I can tell on the highway at 70+ even.

Here is the pipe I had been talking about, J-pipe. I am also going to look into those spinTech mufflers. As of right now though, I am liking the sound/loudness of the super 44 series.

True dual exhaust with a "h pipe" or "x pipe" would be ideal. You can also run a resonator to reduce drone.

Never heard of it, looks like it works wonders according to every link I looked at on google. My concern is the exhaust "hitting a brick wall" seems like it would make a choke point and rob power. Maybe others with experience will chime in

Yeah Science *****!

LoL! Sorry had to do that. This is a pretty awesome bit of physics though. If I wasn't already on love with the spintech sound, I sure as he'll would look into this more with a flow master or other chambered muffler.

I`m going to do some looking around with this `J pipe` and see what I can find. Also on how it work on a vehicle like my truck.

Just a little input and further clarification on a few things:

the flowmaster 10 series is the loudest street legal muffler (it's street legal but if you hammer the gas, I'd imagine they may pull you over for noise violation eventually) It will drone and it will probably drone like hell.

The flowmaster 40 series and 44 series are loud and deep and will also drone... They're slightly bigger (longer) mufflers and are therefore a bit quieter and deeper but still loud and still drone a fair amount

If you want something deep but that won't drone from flowmaster I'd recommend the 70 series stuff (may as well get their whole cat-back system at that.. sounds good no drone and sounds strong, certainly not too loud)
They have a 50 series and super 50 series... one guy I know told me the 50 series drones but I didn't get to ride in it to experience it. There's no way the drone could be bad at all on that.

As for magnaflow, they offer a cat-back system also and I really don't know much about it as I wanted a dignified deeper and better sounding tone in the Flowmaster and kind of didn't pay too much attention to magnaflow but a simple youtube search will yield some good results even on these 400's

Borla seems to have some good stuff, I just like the bigger and better name brands

We had a 50 series on a 2007 jeep grand Cherokee 3.7 v6. Even with a resonator, it droned like a mother! All new cat back. Sounded good for a v6 besides the drone though.

I'm really surprised a 50 series would drone that much especially in a v6. I'd think some of the drone would be minimized if the exhaust were run all the way back on a truck but it's good to have more confirmation that it definitely drones. I've been considering getting the super 50 series or 50 series HD for my truck in place of the 70 series big block but I just don't know
