Do you fit original exhaust collector sleeves with ktec system?

As title says, for those who have a ktec system, have you retained the original collect sleeves?

Cheers

Tim.
 
Yes that's what I meant. Damn exhaust is fitted but doesn't have then on. Do they serve a purpose or will I be ok without them?

If you mean the two metal pieces that the pipes sit in within the diffuser then yes you do.
