Walker Muffler & New Truck Pic

[Morse]

A couple days ago I had posted about straight piping my 05. . It sounded horrible (tinny) and also resonated in the cab. . I just installed a #21471 Walker muffler from NAPA ($79) and it did the trick. . The truck is once again very quiet in the cab with windows up. . No resonation, though it's much louder than stock outside the truck. . It has a low moan that turns into a loud turbo whistle at higher RPM's. .

I couldn't get my pics to post. . It said they were too large...

Go to the First time help icon above, and click on FAQ. There is a procedure for resizing photos to post in the forums or readers rigs. Good to hear you are happy with the muffler. Is it one of the 51" models or a shorter one.
