Upgrades and Aftermarket - 6.0L EngineUpgrading and adding aftermarket equipment to your 2003-Up Super Duty or Excursion with 6.0L Power Stroke diesel engine. Please confine discussion of topics in this forum to those items that are specific to the 6.0L Power Stroke engine.
Has anyone dissected a 6.0 stock down pipe? A vendor explained to me that there is a section of the stock down pipe with a baffle/resonator in that section. I am assuming that it is for sound reduction.
Has anyone compared/recorded a system like DDPI with and with out the CAT Turbo back for the sound. I am curious about what impact the factory down pipe has on the turbo whistle.
Mark???????
Logic would tell me the baffle is there for noise reduction. I would not think it has much emissions impact.

I haven't "dissected" my downpipe, but there is some sort of cannister in the downpipe just before the cat on mine. I was wondering what it is. It's wrapped in the foil stuff they insulated the downpipe in.
Any ideas?? Soot trap maybe?? [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Could be a section of flex.
This would allow the engine to move on its mounts with the new torque #'s all the while allowing the remainder of the exhaust system to remain stationary.
Could be related to the drone, maybe, maybe not.

I saw mine after it had been dissected while putting in my DPPI system; that "canister" is some sort of resonator, probably to curb the turbo whistle a bit. No soot trap, no pre-converter, no witchcraft, no rocket science(just sounds that way). Oh, and no flex pipe either.

That would probably explain why there is way more turbo whine in the turbo back systems vs. the cat-back systems since everyone seems to agree that the cat is not very restrictive.
