I finally broke away from my Flowmaster and Banks mentality and installed a Magnaflow exhaust today. Much better tone and sound, perfect at WOT and just right at cruising speed, but it still makes a ruckus when YOU want it to. I also compared it to the IMCO by listening to one and driving an IMCO equipped truck. The IMCO was annoying and just a bunch of nosie... no real tone or benfeits (straight pipe sounded better)

Plus the Magnaflow warranty beats the tar of the those echo-box mufflers of like Flowmaster and Banks.

I am definitely a convert. Thanks to all of you that have led me to Magnaflow.

 

Pretty nice isn't it??
I was impressed myself!
Now I can't wait for Troyer to tune my truck!!!!

 

what kind of truck and engine was the imco muffler running off of? Do you know which imco it was, the 2 chamber or the extreme? Can you describe the difference in sound between the imco, flow, and the magnaflow? I like exhaust that I can hear rumbling at idle or lowly while driving (little or no drone), and one where I don't have to get all over it just to hear the best part. I want to hear the best part at takeoff, a smooth growl, and as you pick up speed.
