2011 Triple Cat Or Not

There will be a cat in your system and every other bike since 2004/5/6. The cat is found in the "mid-pipe" section and not in the cans or the supplied link pipe (if any). If the cat has been previously removed from the exhaust (before you owned it?) adding an after market spec exhaust end can would make the bike louder than the makers of the exhaust would have anticipated. As a rule of thumb thou, any after market exhaust will be 20-40% louder than the stockers which is good because the standard exhausts on the triple are weak as f%^k

 

hey, on the upside if the cat has been removed and done properly you've got 6-10bhp more than a stocker!!!!

 

Ive not removed one on the triple, but on most other bikes its just as andyc1 said, their just drilled out with a spade bit or sum such. So there wont be any visible difference. Guess what you could do is remove the pipes down to the mid section and slowly/carefully insert a length of wood or plastic and see how far along the mid pipe it will go. If it makes it past the bulge its safe to say theres no cat.
