From what I have found so far, there are types that go where the collector meets the side pipe flange, and types that go into the turn down at the end of the side pipes, so yes you would have one at each side, wether you could put two per side I do not know. I also have not had a chance to contact the manufacturers to get a better explanation of installation, but I am liking the cone inserts in the turndown that Dynotech offers - the Vortex insert cone is what Deano listed it as. It looks simple to install and remove by the pics, but I do not know yet how they attach. More investigation is needed.

If anyone has used the cne inserts I would like to know.
