Ok... I hate to give exact numbers since the dyno testing was not back to back while the car was still strapped on the dyno... We did try to make the test as fair as possible though! That being said I can honestly say i FELT a performance difference in the mid to upper RPMs... There was enough difference that I paid to have the car dyno'ed... and the dyno did confirm that I was in fact feeling the gain... so I don't want to put an exact number on it, i do feel confident in saying there was a gain with the AT... make sense?

wow so that would be a possible 10+ hp and tq over stock by just switching out the muffler. I'm installing mine tommorow so i'll see how it feels

good stuff. hopefully this is proof enough that there are worthwhile gains from a "good" hi-flow muff. there have been some members chiming in here and there that aftermarket muffs dont make a difference or only give 2-3hp at best. seems like it all depends on which muff you got.

The only thing I don't like that's happened since I got my AT is the fact that when I sometimes floor it, it starts to pick up but suddenly hesitates, then picks up again. It doesn't happen everytime, but if I was a track person it would definitely not be a good thing.
Also... I had not heard about this reliability issue with this exhaust... should I be concerned?

Installed my aeroturbine yesterday afternoon, definitely an improvement over the stock sound. It sounds a little funky around 3-4k RPM though. Will the sound change over the next month or so as it breaks in?

It will get a bit deeper with time, though. Mine took about a month before it broke in completely.

Hey guys, sorry for bumping an old post.
I have been researching a muffler for my 05 v6 and I was almost sure to go for the AT. Now I am in doubt cuz of the high-pitch in higher revs.
I am trying to find a recording of the Maxthunder on a single system to compare but I cannot find it. Legendlime05, do you have a video of your car to share?
Thanks
