RE: Best Exhaust for the HEMI????
I think the best looking that Ive seen is the Corsa, I dont think any of them will give much of a HP gain, maybe 2-3 hp, the hemi exhaust is already pretty good, just doesnt have a loud enough note to it.

RE: Best Exhaust for the HEMI????
take a look at the AeroTurbine, it is the newest high performance muffler to hit the market
(I tried posting a sound clip for you but was unsuccessful, you can hear it at www.aero-exhaust.com)
here is a little bit about it:
The AeroTurbine is a packless, straight thru design, high performance muffler. The company spent over three years in Research and Design to develop a muffler that used the Principles of Thermodynamics to reduce temperatures (EGT's), increase horsepower, torque, fuel economy, and reduce engine wear and tear. With it's fully welded 304 Stainless Steel construction, the AeroTurbine is nearly indestructible and guaranteed to last as long as you own your vehicle, backed by a manufacturer's lifetime warranty. Weighing in at a mere 6 pounds, the AeroTurbine is a natural choice for the performance minded enthusiast.
Universal Application
With sizes ranging from 2.5" to 5", whether you drive a sport compact, muscle car, SUV, truck or diesel, you can guarantee there is an AeroTurbine for your application that will reduce your vehicles exhaust temperatures (EGT's), as well as increase it's power, torque, and fuel economy, while reducing engine wear and tear.
Learn How It Works
As the exhaust stream enters the AeroTurbine, it expands to fill the cylindrical chamber. This expansion slows the exhaust stream, creating a lower pressure at the inlet or scavenging effect, similar to that of a header. The exhaust stream is then split via an airfoil cone with an orifice similar to a conical jet engine. The outer stream accelerates to a higher velocity as it flows around the cone and has a lower pressure than the core stream, which is traveling at a slower velocity, and a higher pressure. The two streams are reintroduced via perforations in the center core. The high pressure inner stream is initially drawn out of these perforations as the gas attempts to equalize the pressure differential between the two streams. As this occurs, the change in direction of the exhaust stream causes destructive interference, which deadens the sound. As the pressure is equalized towards the rear of the canister the exhaust gas is pushed back through the helically arranged perforations in the center core, which spin the exhaust stream, causing additional sound cancellation, reducing turbulence, and creating a vortex that enables the gas to more efficiently exit the muffler.
This revolutionary design has been tested and proven to flow more exhaust gas than straight pipe. The quicker you can draw spent gases away from your engine the more power it can make.
Race Proven Performance
The AeroTurbine muffler has stormed onto the race scene with great success. From Rolex Series Grand Am cars, to being the official muffler both Nascar and of UROC, the AeroTurbine has become the muffler of choice for those looking for the ultimate in performance.
After the Rolex Grand-Am Series tightened noise restrictions, the Chip Ganassi team requested mufflers from several leading manufacturers, including AeroTurbine. After testing all the mufflers on their race cars they announced the AeroTurbine was the muffler of choice for the team. "We are now using AeroTurbine mufflers exclusively on our Grand-Am cars. They simply outperformed all the others we tested. They are lighter, fit great in the room allotted to them, and the best thing is they make horsepower," said Jeff Lohman, assistant engineer at Chip Ganassi Racing.
AeroTurbine mufflers have also been adopted by Riley Technologies and the SunTrust Pontiac Teams, who both compete in the Rolex Grand Am Series, after testing the mufflers on their cars.
Brandon Riehl who races in the Nascar AutoZone Elite Division, and most recently Rusty Wallace are also both using the AeroTurbine.

RE: Best Exhaust for the HEMI????
I have a Gibson single in/single out on the way, I will be posting pics and reviews as soon as I get it. I did alot of research and found that the si/so is the way to go if you want max performance gain. I also didnt want anything overly loud so I stayed away from the dual exhaust. I think the first response of it being a matter of opinion is true. You wuill get 100 response each unique that think their exhaust is the best. For me the Gibson is easy to put on yourself at home, cost less than 300 dollars shipped to my door, has dyno proven performance numbers and I have talked to many with it that love it and said it was not too loud but has a deep tone to it when you punch it and gives the hemi the growl it needs. Those are the reasons for my purchase. Some sytems (CORSA, magnaflow and borla) may be nicer but are wayyyyyyy too expensive for an exhaust. I have seen prices up to 800-900 dollars for some. Thats more than 3x the cost of the aluminized gibson. Well, enough of my soapbox. Whatever you choose I am sure it will be good. If you go with flowmast read up. I have seen too many bad reviews on the flowmaster (this is not to get flowmaster users mad, I am sure there are happy flowmaster users). There is an actual flowmaster made specifically for the hemi, the 50 series hd. You will find that the hemi requires a larger muffler than many of the other flowmaster models.
