When they first fired it up I was totally impressed. Sounded incredible. Just enough of a rumble to remind you of what is under the hood. Under load....... well we are going to have to work on that one a bit more. Definite drone. There is a bit of a harmonics issue also. At certain rpm's there are some noticeable vibrations due to the new exhaust. They did not exist before. I have been unable to test for performance improvements but there is definitely a better throttle response. Not sure if that is because of wishing it would or it actually does respond better. I will get numbers as soon as this stupid rain stops and the roads dry a bit.
Quick 10 or so mile run at highway speeds shows a small improvement in gas mileage. Too early to really tell. When I go back and forth to work over the next week I should be able to tell.
Oh, what kind of mufflers did I use??? Aero-Turbines and added their resonator. Two AT2525's and two AR25's. Love the sound at idle, need to work on the sound under load.
Will post some pics after the rain stops.

Here is a link to a video file that shows how the exhaust sounds. Love everything about it except for a drone under load at about 2000 rpms that will rattle the interior. Will start looking into this more in the morning.

Do you have any drone problems?? Say around 2000 rpms under load? Sitting in the driveway it won't do it. Gotta love modifying these cars.

i had teeth shattering drone in the cab between 1900-2100 rpm....this was just the AT3030 on there.....drove around with it for a month driving neighbors crazy and myself nuts with how loud it was both inside and outside the cab
put on the AR30 resonator and it got rid of almost all the drone inside the cab....i have very very little drone now around the same rpm ....its more noticeable when the engine is cold, after it warms up and has been running for a while the exhaust note changes
the drone is so minute now that it's very tolerable when I'm driving, have passengers, and can now listen to the radio at a normal level

If the initial test of the performance change is correct all I have to say is :dropjaw:
I haven't looked at all of the numbers yet but on my way to work I stopped off at the road that I do my testing on to do a quick run. Quick was an understatement. I will try to duplicate this result tomorrow morning on the way to work again. Before I installed the exhaust my average run of 0-60 was 6.17 seconds. This morning I did a run and the accelerometer came back with a 0-60 time of 5.47 seconds!!! May have been a fluke don't know yet. HP calculation came back at 358! ESP was on and when I launched she lit the tires up good enough to make the ESP light flicker once. I didn't think it would spin the tires that much so I didn't turn off the esp. Again this was one run and I have not tried to duplicate the numbers. Will try again in the morning.
Gas mileage has shown an increase of about 1 mpg this morning. I will see what the average is after 4 or 5 days to really see the difference.
So far I am impressed with the mufflers. As soon as I get the resonance issue fixed they will be perfect.

Wooohooo, that sounds sweeeaaattttt !!!!
Nice job MM... Can you run us some sounds while the car is underway ???
Keep up the good work....

Sure. I plan on doing some inside sound clips in the next couple of days. I re-ran the same road this morning with a 0-60 time of 5.55 seconds so the time is a duplicatable number. I may get crazy and take her to the drag strip and see what she will do in the 1/4.

okay MF, I've read your posts... you can't be too far from Lawrenceville, GA (metro Atlanta). I'd love to see your car and see if mine can keep up. Let me know...

Sounds good magnumfreak....now let her loose on the drag strip and start counting the 13second time slips!

Nope just a couple of hours or less (depending on how fast I wanna go). I live just outside of Augusta GA (about 125 miles from Atlanta). We need to have a get together for the southeast pretty soon. There are a few Magnums and 300's around. Would be fun to get together.

I have an Aeroturbine 3030 on my Hemi (Ram 1500) and I removed the factory resonator when it was installed. It was super loud when I first got it put on, but it honestly seemed to tone down a bit after a 1,000 or so miles on it. I do have a pretty strong resonance issue in the 1950-2050 rpm range though. But its not enough to make me wanna alter anything. I love the sound though, its awesome and my 5.7L Quadcab only gets .1 mpg less than my '02 4.7L! I attribute some of this to the Aero, even though i put it on with less than 800 miles on the odometer. Your setup sounds awesome though man, I wanna get one of these cars when its time to replace my wifeys!

So... 85 degrees outside, 100% humidity (thanks Hurricane Jeanne) ESP on. Will this car spin the tires??? Click below to watch a video.
Sweet man thats awesome....sounds like my R/T in the cab! Nice job!
Now get us some times!!!
