2009 G6 GT GT-R Exhaust

Ok So I have two questions...first when you put the gt-r exhaust on 2009 g6 i kno its different because the 2009 has a third cat...will that affect performance? also what about sound will it sound any different? Does anyone know how to get rid of the 4k rev limiter on the g6 it really bugs me when im in neutral and im stuck to 4000....thanks

from what i've read it will have only a small effect on performance, not sure about the sound.....you have to get a tune to get rid of the rev limiter.

This is notable in that it's the only hp # I've ever seen Sam quote, but per him the 3rd cat results in a 6 hp loss.

I haven't heard any others in person to compare but trust me the sound is still =D
