I would expect bugger all change then and think the current TORs tune should be fine.
You wont get anymore from any exhaust upgrades etc until you ditch the stock under seat air induction - the K&N does stuff all there besides reduce maintenance replacement costs.
Unless I am missing something here I still think 8 RWHP would be close. I base that on my own upgrades. Had a set of TORS and Ramair dynoed at 139 RWHP, added the DP Outlaw shorty's and crossover and dynoed at 147. Only change was the DP Outlaws and cross over. Same tuner etc.

After reading everything again, I believe you are all correct. The cat bypass was already in place so the majority of the gains were already made. Apologies for any confusion. As long as the bike was already tuned for the bypass and TORS, the DP pipes will make only a small difference. Not sure if I would be using a TORS tune though, still think it would be lean on that
