I have personally had pipes made up for htis configuration on my last r33, on my new r33 i have the kit which requires hte hole cut.
IMO i belive the first option using hte two stock engine bay pipes is better. I feel better response and better cooling performance.
So yes u can just buy any front mount and get the pipes made up, Gilmore racing developments did it to mine way a few years ago, they are in brisbane tho.
