Y-Pipe Thoughts?

Anyone seen heard or know anything about these?

MBRP Heavy Duty Up-pipe Kit - Riffraff Diesel Performance

BD 6.0L Turbo Feed Up-Pipes - Riffraff Diesel Performance

Side note, does anyone have an old/blown y-pipe laying around that they might want to get off the old parts shelf?

I'll be ordering one next week. Not sure whose but getting one. You can get just the stainless weave bellows themselves cheap from ficmrepair.

I have an MBRP. Needs a dent to clear the 90* elbow on my regulated return system.

Is the flex joint or bellows really needed? I was just thinking that everything is mounted solid to the turbo, so what are the pros and cons to having a bellow/flex joint or not.......

I am actually leaning toward the BD y pipe set up. mainly because of going to the BD exhaust manifolds also.

Anyone here have any experience with the BD stuff....

The way I understand it, Sinister was selling up pipes with no bellows or expansion joints, they all cracked, and Sinister told everyone to **** off, no refunds. The bellows or expansion joint is necessary, because the pipes expand and contract when heat cycling.

I'd be using Josh to re-do mine when/if they need re-done.

PPE makes one also just wrinkle belly with inserts, my diesel guy said that in the woven section is where they fail, stock ones, my PPE has been on for 30k so that's not much of a test, but he was impressed with the pipes.

Those pipes are a little pricey,I'd just fix the flex part and save the bucks for some other mods.

My passenger side bellow was leaking causing exhaust to come into cab when vent was on. So i bought the sinister diesel ceramic up pipe with slip joints n not bellows. I was very impressed. It also came with a very good warranty and was a breeze to install. Just figured id give you another set up to look at and research. Good luck.

Looks like the BD pipes would also have to be combined with an EGR delete...maybe its just the picture?

Lots on the Web but if you're trying to determine if yours is bad the quick and easy is to look for soot. It's pretty noticeable. On another note looks like I went with a sinister unit curtousy of my shop.
