I have a Magnaflow muffler in my RS and would like to know wich muffler would I be better off with a Magnaflow or a flowmaster 80? What is the diffrence betwen them?

 

Who makes the Magnaflow? Dynomax? I wouldn't waste the money if you're looking for performance, but if you don't like the sound it might be worth it.

 

Yes dynomax makes magnflow but it is already instaled in to my car and i just wanted to know if i sould change it later on down the road because i feal like i could get better power out of a flowmaster but i was not sure

 

Flowmaster 80 is an awsome upgrade. I felt noticible gians in acceleration and et's. At first is sounds quiet, but once they break in they sound really good. they get pretty loud.

 

how is the magnaflow bad for performance?

 

Hey james, I like that pic, hehe.
I inspected a bunch of mufflers like that at an exhaust shop before I settled on my magnaflow. Im very happy I did so far, I like not sounding like most of the other cars around here. It sounds pretty good with the 3 inch cat back and high flow cat. Now I just have to do something about those stock manifolds and y pipe....

Oh, I forgot to mention, magnaflow is actually made by carsound.
