All the power is made in the first 3 feet after the heads and sound will be great too. Then you don`t have to frankenstien the back half of your AMG exh. for sound and virtually no power gains..

So will it ? Yes I am a squirrel modder. Saving dolla$ for wheels
You could replace the secondaries with high performance racing cats (AMS posted some ebay auction that sold them pretty cheap) that would net you close to the same sound/performance and should not reduce the lower end torque.
Maybe someone more knowledgable will chime in.

I am not too bothered about any gains i just dont want to loose power, I am in need of more sound really.
If i replace the 2nd cats what will happen with sound and power between straight pipes and x pipe?
