Why three stacks?

Screw CARB.

All they've ever done is make our lives more difficult and make it moer expensive to run our businesses.

 

Its for sale in L.A. doest say enough

 

That is good, I just looked at 2 different 389's in OKC and they both had the 3 pipe set-up, and then they had several that were set-up regularly. From what the salesman told me, it is just an option you can order.

 

Probly a California thing.

 

It could be a truck that was retrofitted for DPF since it is in Cali.

 

He swapped in a W motor. Three turboes need three stacks. hehehe

 

The ad has pics with the rubber cab extenders in place and no extra pipes. Wonder if this is a dealer's attempt to chrome it up. If so, they're doing it wrong.

 

The one in the middle is real.... ya can tell by the heated temperature marks on the bottom of the pipe below the muffler.... the two on either side are fake and only for show and have no heated temperature marks...

 

Okay guys, y'all need to think before you type. The center is obviously factory, the ridiculous small radius bends are on all the 387's (And one of the reasons I passed on buying one when they came out.) The dual exhaust setup on these trucks is just outboard of the frame rail, basically a twin on the left of what's already there. Look at how the fake pipes are attached to the back of the sleeper, they are not intended to ever be hooked up as actual exhaust.

This is simply a dealer looking to move a truck to the first billy bigrigger he can get financing for. Probably the same idiots who bought the mid-roof Columbias with the twin stacks up the side and the air horns on top. Looked like something a 5th grader would have come up with, but it made it an o/o truck! Yeah, sure it did.

 

Well then.... They should put some blue lights on the inside of the windshield.
