Engine/Transmission (1994 - 1998) MBRP Question

[KEnglish]

I've had a MBRP SS409 4" exhaust on my 97 2500 for about 2 years and it's recently gotten really loud. What's the life expectency of these mufflers?

I looked at my receipt [ complete system ] they did not itemize the parts & numbers , so I can not see if we have the same .
You should go to the user control panel and fill in the details of your truck & mods , easier to answer ???
Same with muffler , give a description also , with the ss in number I would guess stainless , mine is aluminum .
Haven't heard anything about failures .
