Hi I cut the cat out of mine & found a huge differents in performance,
I used to run a single MTC can but found it far to noisy & could not get rid of the
Back firing popping, I have stage 1,2&3 with Kev mod & eliminator, bike runs so
sweet now, smooth no popping & plenty of grunt, really glad I made a decision to remove
the cat as I was finding it hard to gel with the Ten.
