I wonder if one of the GM dealership employees on this forum could look at a 2005 ECSB that has the L33 5.3 Aluminum blocked 310 HP motor. I would like to know if they have changed the exhaust any. Say from the single in and out to the dual in and single out muffler?

You can always go by the dealer and check under one of the 2005 trucks

we're ordering one next week here, but i haven't seen one yet. i'll check the parts computer this morning.

LX331

I should have one hit the ground in a couple of days but im not to sure of the exhaust. The L33 is only available on 4wD models.

The L33 Has The Same Setup As The Lr4 And The Lm7.

Lx331 Is Right It Only Comes In 4wd Ec Trucks
