I recently replaced my stock exhaust with an MBRP 4" system, including downpipe.

My question is this: will my original downpipe (2004 LB7 CCSB, no cat) fit a 2004.5 LLY ECSB with a cat?

Please advise. I apologize in advance for my ignorance.

not down pipe, front pipe..........................as of yet their are no downpipes available for the stock turbo.

Yes, it's a direct bolt on.

Both of the above posts are correct.

Sorry for the nomenclature snafu. Thanks for the info, all.
