What is the advantage of paying $100+ for a FM or MF over a flowthrough glasspack from someone else?

ive got the glaspacks and they sound throaty , but i would prefer them to wear out soon so it can be louder. overall they are decent for stock.

I have a v6 05 and had duels put on with flow masters and at the dealer ship just by sound they could not tell it was a v6

SLP loudmouth or power-flow...they are both really good systems and i have talked to performance shops here in Houston that said that they dyno'd to give the best gains b/c of the no restriction pipes. the power-flow are single chambered and the loudmouths are basically glass-packs.

Just as added info:

both are really cheap and from what i have heard, it is b/c they are trying to get their hands in the mustang pie since we said "so-long" to the camaro and firebird. The guy told me that the SLP's have made an impact on Mustangs already and the price will more than likely be going up in the near future to compare with bassani and magnaflow and all of them

The loudmouth wont sound like a glass pack though will it? I would really love to hear the loudmouth on a GT

there is a guy that has a soundbite of the SLP axle-back system..try doing a search for it.

i wish these muffler manufacturers would put the cfm rating somewhere. its really important to get a muffler that matches the rest of the exhaust and the whole rest of the engine
and nothing is gained by paying twice as much for 50 percent more flow when you are already where you need to be.
