I'm used to oval track cars, where some companies claim that a Y setup to a single exhaust increases breath of the powerband and power. Sort of an 8-2-1 setup.





The issue on power seems to be design of the merge. Burns describes an X-pipe as two Y-Pipes joined:





To work correctly they must be a 2-to-1 merge collector.

Question: Does someone build these for F-bodies? Y-bodes? Monaro/GTO?

And do they work?

Thanks,

David

Flowmaster does......i have one on my car, 4" in and 3" out. I think it works great, cuts down on the rasp from my LTs and RandomTech cats because they are virtually like having an ORY and it flows great!

the flowmaster merge is dual 3" in and 4" out most people step it down to a 3" then for there catbacks unless they run a 4" catback. All the Good Y pipes use this merge
