Anyone running stock pipes with Decat?

[redrocket]

I'm just curious if anyone is running the Cat Elim with stock pipes and underseat K&N. And if you are still using the stock tune or if there is one that is better for this setup. It seems to run Ok but I did notice it's pumping out more air with more force. Will the ECU learn and correct a lean situation? I really like the new mellow sound. One of you Caps suggested using the Tors tune. No, I don't have a Tune Boy. Thanks!

I use to run like that and Triumph just put in the TORS tune and i never had a problem.
