deepest sound/grumble?

So I'm trying to figure out what would be the best setup for my exhaust, at least for now til the engine gets built up. I'd like to make it a little bit louder with a low exhaust note (or at least as low as it'll get with my 3.8). All three would be stock headers/cats, replacing from the resonator back.

1. Mid-mount Magnaflow with built in X-pipe, dual 2" pipes all the way back
2. Mid-mount Magnaflow straight through, H-pipe, dual 2" pipes all the way back
3. Mid-mount Magnaflow dual in, single out 2.5", Y'd to dual tips in back

Thoughts on how these setups would sound?

The v6 is a very smooth sounding engine, I dont think there would be much of a sound difference between those choices...so I would go with the cheapest, #3.

I can get the magnaflow resonator and tips on summit for about $100, and I know a guy locally who can bend and weld the first setup for $150, hence why I was initially leaning towards that option. I really don't want my exhaust to sound ricey and I've heard an H-pipe will provide a little lower tone than an X-pipe on a 6, sound about right or was someone blowin smoke?

the 3.8 is a balanced firing motor so you technically dont need a crossover tube at all. I think the 2-1-2 setup would be deeper, due to all of the exhaust going into one larger pipe. It would be tough to put a muffler AND h-pipe midbody...you are pretty limited on space. I also think you would have less popping if you went with the 2-1-2.

just my opinion though.

Obviously I'm new at this, so can you explain the dyanmic of how all the exhaust going into one larger pipe makes it deeper?

What causes the popping? Thanks for the help Wes

I dont know for a fact about the single larger pipe being deeper than two smaller ones, but i do know that the larger pipe you go, the deeper the sound(to a point).

I've heard air being sucked back into the pipes causes the popping, but im not sure. My 2-1-2 system didnt do it at all, but my current magnaflow dido system does a little bit.

I could be way off on all this, but I would personally go with the 2-1-2 setup for a v6.

True Duals on a V6 might be overkill. Too much loss of backpressure I would think. Go with a 2-1-2 setup. Personally, Im sooo used to that V8 sound that a V6 exhaust (any setup) makes me laugh . No offense though. There is a guy in my town with a really nice White V6 Cougar with true dual exhaust with rear mounted DroneMasters... it sounds sooooo bad. I dont think it sounds deep (or good for that matter) at all. A mid-mount magnaflow muffer mounted at the Y-Pipe would be your best bet (Dual In/Single Out). Ive always thought that Magnaflow sounds deep on any exhaust... 4, 6, or 8 cylinders.

If you want a popping noise remove your cats . If your after a pulsating resonance thru the entire RPM band a H-Pipe or X-pipe setup would create this (but not sure on a v6). My car droned soo much with a 2-1-2 setup. After true duals and removed cats (and it broke in) it pulsates nicely... and pops a little if im high in the RPM band and let off the gas .

Sold my Cougar . But I am in the market for another MN12 project!

I think I'll end up going with a 2-1-2 setup for the time being, just swap the resonator with the magnaflow and Y it out to tips. When I get some more power under the hood (god knows when that'll be) I'll redo it and hopefully get more tone outta the engine itself. Thanks guys!

I have a midmounted glasspack with 2.5 duals going out the back. It sounds good. Not Ricey, deep at the lower RPMS
