Looks great Natty, I saw a S4r on a run out a few weeks ago with Termi's like yours fitted and thought it sounded a bit quiet, not as loud as my S4 with Termi's, so removing the cat must be the thing that gives it the roar back
Do the pillion pegs not fit with your system or have you just took them off, do you happen to know if they fit with the other "lower level shotgun" Termi system? Reason Im asking is I cant stop looking at pics of the new stripey red 05 S4R! So MAYBE next year
