what does it take to make a LLY duramax as loud as a LB7? I have both with a straight pipe and the LB7 is much louder.

I just ordered the dynomax pipe from summit racing in hopes of it being louder. I hope it works. Wolford 08-03-2004, 05:26 PM i did and it still isnt as loud codythom 08-03-2004, 06:29 PM you removed both the cat and muffler? About how loud is it with both off compared to LB7? I have my muffler off and the cat is about to go, so I hope it makes it louder. I have asked this question about making it louder, but nobody had that many ideas. Like you said on my 2002 LB7 with a straight pipe, it sounded like a semi.
