Seems like I have read it before that the magnaflow catback system can change it's sound characteristics over time. Can anybody substantiate or elaborate this? I want to say that mine still sound really good but seem to have changed a bit.Seems like I have read it before that the magnaflow catback system can change it's sound characteristics over time.

Over time it will get louder and deeper. I think its from carbon type buildup somewhat clogging the fibers in the muffler used for sound absorbing

That sounds right. Probably offroad pipe would accelerate this affect -vs- cat'd system due to more particulant flowing downstream. We have a working theory.

It is actually the fibers of the wrap burning off and glazing over making a larger resonance chamber and a smoother flowpath out of the body of the muffler. Typically a glass pack style muffler smoke and smells when they are first installed because of the packing inital burn off of the loose fibers.

And Silver is the expert, I must agree! [sm=icon_cheers.gif]

sounds good to me!

yeah... mine got a lot deeper after the second month!

I agree, mine got deeper and deeper and finally leveled off after 2 months.
