I'm getting different exhaust on my car next Friday. My mind is made up, i'm
getting Flowmaster. Instead of getting the crossflow, i've thought about running 2 1 chamber flows after the axle. Has anyone tried this? How loud will this be? Just weighing my options before I may a decision. Will it sound good?

people have been using them on true duals recently. Why don't you just run one muffler? Don't think you need two.

I know I have a flowmaster 1 or 2 chamber (not sure). But, anyways that thing pops and backfires like crazy I hate the damn thing. It is a 1 into 2 flowmaster. I like flows but this just sounds nasty.

Are you interested in performance or sound? Because Flowmaster is in NO WAY the best performing muffler

the single chambers are pretty good

Got proof? Would like to see dyno #s or flow #s that support your claim.

If there is a lack of Performance id like to see it. My numbers are came only and im surprised i put down what i did running an a3. if there is any loss its a matter of 5 hp. but through using 2 single chambers. have you seen how damn tiny they are. they are only 8 inches long.

Too answer your question, yes they are loud. And it gotten extremely loud after I did a cam swap. i love my exhaust. I ll try to get an exhaust clip up so people can hear it.
