I run stock...

 

Has anyone seen a performance or mpg gain with a flowmaster or magnaflow? I know the stock exhausts flow well.

 

The Magna Flow was very loud at highway. I took it to a shop And had them tone it down. Now it's perfect. I love it and it adds that aggressive sound to the engine. I bought mine off ebay for about $300 and installed it myself.

 

I have the cheap 30$ cherry bomb glasspack "muffler".

Sounds nice and deep, at idle and when givin er a little.

It is technically illegal though, because it is a straight through muffler! well at least where i live it is.. but they don't bug trucks around here!

 

Flowmaster original 40. Stock pipe. Low deep idle but noticeable rumble. Crisp roar with throttle. To increase noise out the pipe I would have to replace stealthy stock tip. Flowmaster has clips as well as Magnaflow. Hot Rod sound. Can get a lil backpressure bubble downshifting. No louder than tires.
I tried to load clip and nothing worked. I tried to link it to cardomain and FB, guess video cameras to high tech. Any ideas how to clip it here?

 

I can't get the video to share but on Flowmaster there are links and Streetfire.com. The clips don't give true sound. Delta 40s are a little quieter than regular 40s and 50 less and 70s for stockish level. Bigger pipe more noise.

 

Look on www.youtube.com for sound clips. I very much so prefer Magnaflow.

 

I'm leaning towards magnaflow more and more
