Link? No. Just think about it. How is moving the obstruction 30" downstream affecting anything? The gains in that old TXS setup come entirely from the downpipe, because the stock downpipe flange is a much bigger restriction than the piping size of stock exhaust. But once that's gone, if you don't upgrade all the pipe sizing you don't get much compared to replacing all of it.
