GREENBIOCH said:I get anything but comments about rice. In fact I have to tell people that it is a 6, which surprises many. I think it sounds ricey after 3000rpms and no matter what mufflers you get like it was said before, the motor gives itself away. Oh and an x pipe (in my opinion)will make it sound more ricey and more so if you get rid of your Cats. If you go straight thru keep your cats you will get a nice idle, I have yet to hear a sound clip that sounds like it does when your standing next to the car.
GREENBIOCH said:You can try and get any mufflers you want, the only difference I hear in sound is whether it is a chambered muffler or a straight thru design, chambered is louder and not as efficent performance wise(in theory), straight thru will be less loud(or more ricey as you put it) but breaths better, thats it in a nut shell.

Why Waste your money, Do it right the first time. Obviously your speaking from lack of experience here. How is letting your engine breath a bit better hurting performance again?? Your talking about exhaust temps going down and stagnant fumes in the exhaust system. Your not changing your headers or increasing the diameter of the pipes all the way thru the system, unless you want too for SC, turbo, or Nitrous. So how is a true dual system hurting performance, I don't understand your logic here??
xneox said:The most restrictive part of the Mustang 3.8 stock exhaust is everything behind the cats. That's a fact. Flow-thru duals move peak torque higher in the RPM range...so much that people notice without having to run the car on a dyno. That's significant, and it's also a fact.

CANTONRACER said:I have seen numerous cars lose rwhp on a dyno when the relieved the so called "restrictive" back pressure. I saw an LS1 car jump almost 30 rwhp when he capped his cut out. That was an extreme...but rarely do I see something can from lotsa exhaust.
A larger exhaust is needed when...
You have lotsa cubes...
You have lotsa rpm...
You have lotsa motor...
The 3.8L has none of the above. It is all low end and mid range. So you lose your bottom end and you throw gear at it...woo hoo...your absolutely going no where, sorta like one step back, one step forward...yet your wallet is lighter.
You do not want a short diameter tire, low rpm and geared vehicle. Sure, you thinking your going faster, but your not.
My old Z28 combo ran 1 single 3" dia pipe, no cats. Motor was 389", 3600 lbs, shifted @ 6300 rpm, ran 11.7's@116 mph. Break that down, that is 2-1/8" dia pipe duals.
So technically, your basically running more exhaust than my motor that was over 157" larger, spins 1000 rpm higher and made 2.5 the rwhp.
My new combo, big honking heads, 7000 rpm shifts, lotsa stall, looking for upwards of near 500 @ the wheels on motor and then spray a 200 shot on top of that...I am going with a single 3.5" exhaust..which breaks down to roughly a dual 2-1/2" system.
You would be surprised how many bad cars have smaller than you think exhaust systems...
