Well as I am cutting my piping apart to make new headers,{ because of poor spooling } I found that one of my flex coupling imploded.
Hole is alittle under 1"












I just bought new ones with a lining.

 

what brand is that second one? I'll look once i get home,but i believe my pacesetters are lined

 

wow, that's kinda funny, and not at the same time

 

Iam not sure of the brands. The new ones I got say ; BRAND NEW EXHAUST FLEX JOINT PIPE

CONSTRUCTION: 304 STAINLESS EVEN THE CRIMP RINGS

DIMENSION: 4" LENGTH X 2.5" I.D.

LINER DESIGN: INTERLOCK LINER(GREAT FOR SMOOTH EXHAUST FLOW SPECIALLY FOR TURBO APPLICATIONS).

 

I need to find a non stainless steel one...seems to be a bitch to find with lining

i will double check friday, but check on summit for the pacesetter weld on ones. 99% sure theyre lined. I have several laying in the garage

 

That would give you spool up problems! damn!

 

That's crazy.... Anyone else see this before? Now I want to hack my stuff up and check it.

 

Ive seen this numerous times on the turboforums! It is the reson why i dont want to run them but people said my headers would crack (even if mounted to the motor). So im going with the lined ones for sure!

theres a vendor over on theturboforums.com that sells "turbo safe" flex couplers with the lining in them

 

Just looked mine up - it is stainless ribbed.... for pleasure

 

I've seen the cheap ones do that before also, definitely get the good ones.

 

They especially do that from extreme heat... like when you don't have any timing in it
