Hello everyone,

I am researching exhaust modifications for my Duramax diesel truck and keep coming across discussions about delete pipes. I am trying to understand what a delete pipe actually changes in the exhaust system and why some owners choose to install it.

How does it affect engine performance, fuel economy, reliability, and maintenance in the long term? I am also concerned about emissions compliance and inspection requirements in different regions. Are there legal risks or penalties associated with such modifications?

I would appreciate insights from experienced owners on whether the benefits outweigh the drawbacks in real-world driving conditions please.

 

thanks in advance for any help
