Baffle type exhaust tip

[wolfcreek]

Talked to Freightliner and all they could tell me about this type of exhaust tip is that it was made for heat dissipation. This is a 2009 model with the 340 cummins. He did mention something about the regen process being involved. Is there anyone that as change these out to the regular chrome turn down types, and does it "really" matter that much?? Thanks!!

The baffle type is rusty and looks terrible, I am trying to help out a friend on this.

I have changed out two on friends coaches (a 2008 and a 2015) and they haven't had any issues.

I changed mine. Exhaust now comes straight out to the side, I've not had any problems.

You say out the side I was thinking about the one that just comes out and turns down. The same type most RV's have on them now. Thanks!!

Baffle type exhaust tip

I don't think an engine manufacturer would make such things unless they were required. I think there is some federal rule that mandates these things to better dissipate the diesel fumes. The newer busses in Lexington have exhaust at the roof that end in big wide thick open ended triangles. Also, look at the GM and Ford diesel pickup trucks, these have exhaust tips with "vents", baffles, or whetever.

A smog check, where required, might be concerned with a non-standard exhaust tip. But "might" is highly unlikely.

The exhaust tip is supplied by the body builder. My 2012 Phaeton has a straight stainless pipe from the factory and works just fine.


The type of tip that you reference is generally used when the exhaust is terminated "under" the coach and is used to direct the gasses in a downward direction.

I scraped and sanded mine down, and painted it flat
black with high-temp exhaust paint. Looks fine.

I think this is what we will do, since a chrome one cost $321. Can you believe that?

I don't know what size pipe but I got a turn down tip under $100
DIAMOND EYE 4418TD TURN DOWN TIP 4" X 4" X 18" TIP ( item: 200950728659
ebay mine was actually a 4" pipe to 5" stainless down turn.

I was told that the baffle was to keep from sooting the air filter by pushing exhaust gasses further from side of coach.

I changed mine to a stainless turndown. No problems found.

Lots of stainless turndowns on Ebay, mine was less than $70.

The original was rusted badly, and even when re painted ugly. And no longer available as newer models went back to the regular turndowns.
