I think if the motor revved faster it would sound more exotic no matter what exhaust setup is on it

Good point... revs are also a sound factor under load.

Well you can make it rev faster if you get more aggressive gears. The g37's come with 3.91 gears stock. Also, I think my car sounds better than any g37 i've ever heard. less rasp and deeper.

2012 Mustang v6 BBK Shorty Headers - YouTube

here is a genesis coupe 3.8. it's engine is based off the g37 engine... almost identical other than the .1 change in displacement. it has an exhaust too here's how it sounds in that same position. it comes with 4.19 gears stock. which sound do you prefer? there are axlebacks that can get the 3.7 sounding similiar to this genesis coupe if you want that high pitched wail through the revs.

This is what you need if you want an exotic sounding exhaust.

The genesis coupe v6 was designed by Hyundai/Kia it shares no parts with a Infiniti or Nissan motor. The turbo 4 was a world motor developed by Mitsubishi,Chrysler, and the Korean auto groups.... I believe the key to making the sound different other than exhaust is cam profile. And as others have said ported heads and intake manifolds throttle body and full exhaust. At the end of the day there is not much exotic about the 3.7 no flat plane crank. The most exotic thing about it in my opinion is variable cam timing.

If you say so im not sure on jt because the owner told me that his salesmen told him that.

maybe the salesmen had the 2.0t and the 3.8 confused. Or maybe it was a sales tactic. Either way I think it sounds very similar to a g37. It doesn't perform like the vq engines though, even if its rated at more hp and torque.

From what every one has posted shorty headers are a must to quell the raspiness and Borlas Sports or the Ford FRPP sports seem to have the most exotic sound.

Well I don't know if mine would be considered exotic but I know it doesn't sound like a V8. I've been told it is actually kinda ricey in the upper RPMS, that wasn't exactly what I was going for but I still love the sound.

There is a link to what it sounds like now. Just so you know that was recorded on my phone, the Galaxy S3.

The magnaflow competition is essentially a muffler delete. IT sounds good revving and idling, and low rpms. But it sounds kinda ricey going through the rpm range. I had a muffler delete done on my car for about a month before I couldn't take it anymore and took it off. it made me embarrassed of the car. the magnaflow competition series catback I think has glass pack resonators at the axlebacks? i know the axleback doesn't have any resonators.

I also have shorties but, I left my midpipe and axle backs stock. Did you have your shorties on when you still had the Magnaflows, Powerwhee? I think the shorties would refine the sound a bit but, I'm not sure how or in what way.
