Love mine. If you want the rumble idle and very loud go with the 5" turbo straight back.

kyle u got no cat and muffler?

[KSL667]

kitty ran away from me and the your supposed to trip off the excess pipe because the kit comes for the ext cab/lb and the cc/lb so i just shoved the excess pipe throught the muffler prettymuch deleting it but it is still there

[Duramax-LB7]

can u even here the exhaust at WOT

[KSL667]

in the cab, yes. if you go through a downtown area with taller building you hear it lots too. i havent ever heard it but a lot of ppl say it sounds really nice
