Sweet sounding Duramax Diesel, We also removed the catalytic converter. the power gains were HUGE. It is a must buy if you own a duramax.

  • Were there any trouble codes that came up from removing the cats and mufflers? I guess some people get an EGR code and have to install an EGR block off plate and fingerstick to get rid of the code.

  • No I had no codes that came up.

  • does it still have the muffler? i just bought an 06 GMC and have a superchips flashpaq and boy does it blow some soot, looks just like yours without the bed cap, would really like to know if it still has a muffler though, thanks

  • We removed both the Catalytic Converter and the muffler.

see all

  • which muffler series do you have

  • Fuck honda, American Made Bitches :P

  • @dvdprui well if u have a HONDA then your not very manly to begin with!!!

  • man, this is disappointing. My damn HONDA sounds more manly than this.

    I hate to be the troll, but it's kinda disappointing...then again, I consider a "medium size diesel" anything between 15 and 30 liters, so I might be slightly biased XD

  • How old are you? 10? 11? GROW UP!

  • Nothing like the whistle of a duramax

  • its either a LLY or LBZ

  • is that an LB7 6.6 liter  Duramax???

  • how much does a MBRP turbo back cost and cat back?

    d-max;)
