I am thinking of installing Magnaflow or Flowmaster 40's on my stock exhaust. Most people I talked to or read are using a dual exhaust. Will I change the overall sound and performance using ths stock exhaust with a performance muffler?

Performance will be the same if not worse from a 40 series, Ive heard over and over the only things 40's do is give you a loud exhaust... I do have to say I haven't heard a performance single exhaust on a v6 stang yet though. Im sure it would sound good, minimal power gains in my opinion but you never know!

I figure the power gain will be minimal. Looking for a cheap way out for the time being. I guess I should just give up the cash and go for the duals and a CAI and wait on other things. I have heard more bad things about the flowmaster than good on this board.

I have a x-pipe with flow 40s. They sound loud and mean. My girlfriend gets ##### every time i rev the engine. The set up also freed up alot of high end hp. The car REALLY opens up at like 4 grand.

this exhaust decision is killing me. Now i read a MAC cat-back attatched at the Y or "fake dual" will just give a somewhat true dual sound but NO! power gain. Is this true? This seems to be something that is in my coast range.

THe fact is you can go to a shop and have 2 turbo mufflers installed on a custom Y pipe off the stock exhaust and pay less then half for the set up over buying a overpriced kit. Or buy to MAc flowpath mufflers andtake them to a muffler shop and let them install them

Like the others stated, im a little slower off the line, but in the higher gears it made a world of difference and sounds WAY more respectable. Skip the Y pipe. Any good muffler shop will cut the Y after the cats and install the mufflers right up. With the V6 you wont have to worry about compression.
Here is an MP3 of my 2000 v6 w/ dual flowmasters 40's and 2.25 straight pipes going to the back. (Cats, and mufflers with no x or Y pipe.)

I'm very pleased with it.

Do you mind if we put it in the Multimedia section?

Sure go ahead and put it in the multimedia section. Thanks for asking.
As for other mods as far as under the hood goes, I installed a cold air intake which made a world of difference and also showed me that I really needed the dualies before anything else. It felt like it was being held back. I also installed MSD superconductor wires and NGK Irridium plugs. They made quite an impact as well, but Im pretty sure the car was way out of tune when I got it. Next im thinking either a throttle body spacer or gears.
