7in Round Center/Center Straight-Through Performance Muffler Satin Finish 12772

Everything showed up on time and was in brand new condition. I put it in just because the state changed the law requiring my straight piped Cummins diesel to have a muffler AND a turbo. I bought the straight through model figuring it would not do much, but the insertion loss is quite high. All the noise I like has been attenuated, which makes the state happy. Although, I miss my truck sounding like a dump truck...

Made the straight pipe a little quieter on my LB7, will be looking for a quieter one though.
