MAC catted Pro Chamber?
 

Anyone heard them on the 4.6? Oppions?

They sound almost like an H-Pipe, just a little deeper and they have like a "hollow" tone to it.... Its badass I think. And its quiet, unless you want it to be loud then give her gas. Whats cool is when you are going in a tunnel or passing by barriers, the tone reflects outward and its just badass sounding. The catted ones are slightly quieter then the non catted ones.

I'm in the same boat, I live in Chicago and I have to have cats. I have been really leaning towards the catted pro chamber, I like the sound of the o/r pro chamber so I think the catted will sound just as good, just a little quieter.
