Gutted Cat

I just wanted to post it up in case anyone else would be curious in the future. I gutted the cat on the stock pipe today using a 1" spade drill bit. It had that hard, more metallic material that was difficult to remove.

Difference in sound is hardly noticeable. I really cant hear any difference. So no worries in that department. butt dyno approves, however I am sure there isnt a difference in reality. good mod considering its free, cant really think of any foreseeable negatives, and pretty darn easy to do on the bike.

my lv slip-on $200 from member here..
he re-installed the standard exhaust to sell,
thus recouping $200 cash, added to the sale..

doubt that drilling cat would gain 13.8lb saving
which is the saving from this slip-on replacement..

designed and tuned for cgr250r by leo vince
this quality well fitting italian made exhaust
does slightly enhance power/torque [as well]
without ecu reset or mapping etc..

$ may not be actual hp but they still
buys tires, new lighter battery, etc..

[i also had a response to 'cat gutted'
thinking bazil my staffordshire terrier
had got hold out and done his duty]
