So you know more than the manufacturer? Cool let me know when you make mufflers! I'm very sure they will be the best thing out there!

No, but that's a basic quality of metal. The person you talked to is no engineer. They're a salesman trying to paint their product as perfect so they keep their sales up. Open your eyes and stop being so naive.

And your experience how this changes sound is?
04-03-2009
I work in precision electronics that rely on metals for their sonic vibrations. They have to be kept at a particular temperature constantly because if they change temperature (even if they come back to the original temperature) their sonic pattern has changed. A practical example of this concept they teach us in tech school is things like mufflers. Over time the tone changes and this is the reason why.
My mufflers "broke in" over time and the reason is this hardening of the metal due to several heat up and cool down cycles. They used to drone some on the highway, and they also used to be quieter around town. The highway drone has gone away as the resonant frequency of the muffler more closely matched the inverse to the frequencies which cause drone. Also, around town has gotten louder as this shift in resonance frequencies has lowered their ability to cancel out those tones.
Did the salesman tell you all that?

But what series magnaflows do you have as most do come with a packing material. So that in no way is a comparison to a flowmaster. I've installed alot of flowmasters and had them on quite a few of my cars the tone never changed. Now granted none of my cars or trucks never had converters or resignators. I'm not arguing the point that metal can change with heat common now everyone knows that. Having worked in the automotive machining field I'm pretty familiar with that. But I have never heard a flowmaster change sound or tone. You can call the gentleman I talked to what ever you want fact of the matter is he works there and answered the question knowing I wasn't buying anything from him. I have hooker aerochambers on my car.

well i picked up about .6 tenths in the 1/4 mile and 7 mph. if traction was willing i would have picked up more time. it deff made the car faster and it feels faster to me.

with just headers? that has got to be a big white lie.

No packing in my Magnaflows. They're just perforated three chamber designs. Like this:

nope. old times were 14.6-7 at 91mph. there was a factor tho my computer was reset the day before i do belive and did not have time to relearn its self. thats the only thing i can come up with because i was traping 3 or so mph lower than even stock cars.

I don't know. EVERYONE told me NOT to get Flowmasters on my Contour SVT and I loved the way it sounded. Its personal preference. I wish I could hear them on our GPs in person and not sound clips online. Although I don't think I would get rid of my stock exhaust. I think it has a nice deep sound to it already. I have an 03 Limited Edition. The tips are different then other GPs I see around, I wonder if the mufflers are. Anyone know?
05-04-2009
I cant believe you went through the trouble to actually call flowmaster and talk to a salesman lol!
No its just the tips. Duratec motors just sound good with any exhaust. These 3800's are rasp heaven.

There are three SVT Contour's around the Liberty/KCMO area and they are all modded and sound like epic ass...so idk. The woman said she had heard better on a Honda. I LOL'ed...gots me a keeper
05-05-2009
wait so what does other than flows sound like? rice rockets? or deeper than flows?
05-06-2009
I got Flows I love em...people seem to hate them but meh, I think they sound great for a 3800 car. YouTube - GTP Exhaust
I've head of glasspacks with stock mufflers, Borla's sound fine...but idk...I still like mine IMO...but that's me. It is your car...do what you want.
05-06-2009
i liked my flowmasters when i could keep them quiet with a nice glasspack, but when i first bought the car with straight pipe after the cat and just flowmasters i wanted to shoot myself. when i got it how i liked it sounded good at idle and WOT.
i also hated the drone.
05-06-2009
dude...I know...Try Pacesetter's...straight 3" No cat or Res. into flow 40's
AWESOME!!
Video - xp start up - exhaust gtp
and all I did was add a stock GM Resonator to make it sound like it does in the last post...WOW what a difference
