I'm running an 06 lbz with 4" turbo back mbrp exhaust with no cat. The muffler is a short little muffler that's straight through. I seen a dmax drive by the other day that had a realll deep sound and I loved it. Almost sounded like a big rig or a scummins

Was wondering if anyone had any good suggestions for which exhaust or muffler it may have been.
Was told magnaflow had a real nice deep tone.

A 5" exhaust will be deeper then a 4". That might be what he had.

No a 5" will be a deeper sound. I had a 4" and went to a 5" and mine got deeper

That's what's weird it was a newer style like 05-07. I love how the lb7s sound. Maybe he had a different turbo idk. I figured Id run it by you guys to see what u think
