I'm not going to lie, my favorite part so far are the 4.5" tips.

Do you have any evidence of this or just theory? My car behaves no different with the factory muffler gone. It looks much better from the rear also.

Airflow was clearly a consideration in the stock design. The muffler bottom is mostly flat and directs the air just below the rear fascia. I doubt the GM engineers arrived at this design by chance. Without this design element the rear fascia is going to catch lots of air. There's simply no way it won't. With that said, most people will never notice the difference. I track my car and regularly hit 140+. Any loss in stability would be a non-starter.

But think about it. A big hole under the back of the car can produce a vortex/high pressure area. At sufficient speed it could result in rear lift. If getting passed by your rear tires at 150+ mph is not a concern to you, then go for it. If it is, don't. Back to topic... The AWE system does sound fantastic! |

It looks like a bolt on muffler replacement shield would be nice. That could fill the hole left by the missing suitcase, and get rid of the potential drag issue. For most people they will never realize they lost the air flow, but for others its a most to not mess up the air flow.

I am not concerned with added airflow under the car because my car is a street car. I don't drive a F1 car.

whoa wait a second. I just saw this on the web page
"AWE cat-back exhausts are not applicable to vehicles with an automatic transmission, only axle-backs." Is this accurate? If so that's probably a deal breaker for me.

Guess I am going full send and getting the race axle-back then.

Unfortunately the cat back system is not compatible with the automatics AFM option because they do not have the mounting brackets for the valves. Also with the convertibles, the extra chassis bracing that comes with them will not allow for the cat back system to mount correctly. The convertible can use their axle back system and still obtain the awesome sound.

GM has been using the suitcase design all the way back to the C5 Corvette days. MANY, MANY people have replaced the stock exhausts with non-suitcase systems and have raced these cars on track, and doing a quick search, there does not seem to be any issues of stability or loss on control issues. In fact , at one point in the C5 days, GM actually teamed up with Corsa (which does NOT use the suitcase design) and was a dealer level option. Maybe there is some air differences back there, but if there was any issue of it causing negative effects either with stability OR lifting the rear-end, you would have heard about it AND the aftermarket exhaust companies would have altered their design. People tend to take things like this to the extreme and just run with it. I have had Corsa's on every one of my Corvette's and all of them routinely saw triple digit speeds and NEVER once have I had any issues with airflow or stability. Lets keep things in perspective here and use some logic and real world cases and not our imagination.
