which mbrp should i purchase for my new lbz. i want more sound, as much as possible, and more power. i was just wondering which would be better, the duals or single exit. and if mbrp would be the brand for that. thanks

Answer:
Duals, no cat, no muffler and in that order if you're picking from the top, IMHO.

I like my 5". The sound is deeper than 4". I can't speak for duals

gmcdiesel,

The duals ahve the "look" if you get a front pipe back you'll get great sound volume and tone out of them. If you want the loudest get the front pipe back 5 inch system as was mentioned it's got a deeper tone and more volume too! If you have any questions call us at the office.
