for the better or for the bad?

Ok I just bought some mac pro dumps and will be here on friday...I had flowmaster 2ch w/ dumps, was this a good choice will they sound better. I can hardly wait till they get here. But honestly do you think it was for the better or for the bad to swith, will I gain any more horse by switching?

I'd like to know how it works out for you. I have 2 chamber flowmasters dumped too and was thinking about switching over to Pro Dumps. I don't think the 2 chambers are as aggressive as i wanted. I like an evil exhaust sound, the flows are too calm fo rme.
