I have a 69 oldsmobile 442 convertible with a modified 455. I have dynomax headers with 3" collectors. I was wanting to replace the exhaust with 3" piping through an x pipe to flowmaster 40 series mufflers reduced to 2 1/2 inch tailpipes so I could still use the original trumpet exhaust tips. Is there anyway this can be pieced together? thanks alot!!

I would order the parts and have your local shop install them. They can modify your mufflers to fit that configuration.

You would need to reduce at the end for the trumpet tips. I don't think anyone makes those tips in 3".
