quite high flow exhaust

I want a exhaust system that is higher flowing then stock but just as quite or quieter. I was thinking of installing a glass pack infront of a flow master and maybe another glass pack behind the muffler. Will this work ? Any ideas?

Don't really think you will getting what you want adding the mufflers where you want to. JMO have you thought about adding resonator's ? And some high flow cat's would help also.

For the most part mufflers are the things that are most restrictive to exhaust flow, just slightly better than catalytic converters. Multiple mufflers add quiet but also add flow restriction. The more the restriction to more fuel you burn to provide pumping power off the crankshaft to force the exhaust out.

Restriction is the whole reason behind dual exhaust systems. The typical muffler has a hard time getting to 300 CFM a few exceed that most don't get there. Pipe diameter on the ends has little to do with the problem.

Which Flowmaster they range from pretty quiet to pretty loud and what is this on?

Not to be a smart a** but if you want quiet I find it exciting to drive my wife's PRIUS, the people that don't look before they step off the curb will never hear what hit them. That thing always reminds me of truth in the saying "Loud Pipes Save Lives".

This is true they have a different sound all together seems like to me. been thing about going to some magnaflow's/flowmasters on my truck. Just haven't decided yet But either way if he wants the high flow mufflers and really want's to quiet it down that's what the high flow resonators and cat's are designed to do. IMHO

Just go to youtube and listen to several different set's of exhaust to help you decide what you want. JMO

I have never tried resonators. I will have to look into them.
I say adding a glass packs as I thought the were not restrictive since they are a straight thru design, I guess I was wrong. Being a straight thru design glass pack I figured the fiber glass packing around the outer tube would help cancel some sound and not restrict flow.
I am also looking to do what you do in the wifes prius, you have a prius . No, really I am using my truck for fishing ,camping , and hunting and I dont want to drive thru the woods announcing to all the rabbits I am there. When I want loud I will open the exhaust cutouts.
