Hey all i have a ?.. I have a 05 CTD a want to put exhaust on it from turbo back this will take off the catalytic converter will this void my warrenty???

 

If you remove your cat, then yes. but it's ohh so sweet.

 

It won't b/c diesels fall under a different ruling as far as the cat goes. Now the new '07 models can't be removed. You can replace everything from the turbo back and it won't make a difference as far as warranty goes. The state that you live in may have some issues as this varies from state to state.
