2 flowmaster ?????
I was woundering if anyone has ever put 2 flowmasters on a third gen?
I was thinking of putting one flowmaster were the catalitic goes and one were the stock muffler goes.
But dont now if this will affect my back pressure or anything else. I want to now if this will be a good idea?

Why, it doesn't make sense to do it. You are just inducing more restriction.
If you want a quieter muffler there are mufflers that flow more AND aren't as loud. The lists below were done on a mustang I believe. But the data is still relavent to your question.
