Thread: 2.5" or 3" downpipe?

To clarify that statement.....


You would have to cut then weld a expander onto the end of the downpipe. Which I have NEVER seen.

I have seen weld in reducers though. Such as going from a 3'' down pipe to a 2.5'' bolt in flange. So that it will work with your stock exhaust.

3" or buy headers. cat back is a waste of money. if u want sound, get mufflers.. everyone here is giving u sound advice.............
