HP ratings for mods

Interesting this should come up because I was thinking about this today.
Assuming there is a cat bypass installed...

Is there much difference between TORS and Jardines?
TORS and drilled out stock mufflers? (no endcap or packing)
Undertank K&N and triple K&Ns?

I thought maybe someone here might have the figures.

Look for 135-138 real wheel HP with Cat-bypass-TORS and Trimph Tune...
Adding Tuneboy will get you to about 143-145 RWHP...

Jardines and triple Unis/K&Ns will yeild you 150-155RWHP depending wether you not you do a custom tune.....
