Been looking at changing my exhaust system for something a bit quieter.

I've found a ninja and ninja 2 cat backs in 2.5 " for a reasonable price . I'd hoped the decrease in bore might quieten the old girl down a bit

Anybody else got a full decated 2.5" ninja exhaust on or heard one ?

I had a ninja on my first one wasn't too loud just a nice grumble

Was that decated and do you remember which version ninja it was matt ?

Was 1 I think Yep all decat baby

I've got a ninja 1 but got the cat in still so not sure it's much help.

Cheers for the input chaps [emoji106]

Missed The ninja 1 sold [emoji53]

The ninja 2 in on the bay but he hasn't answered my question about fitment and bore ,so it's not looking good either[emoji57]

Don't really want to shell out much more than £150 on a 2.5 " cat back as I might have to switch back to my current 3" 5zigen system if the reduction in bore size looses spool or power on the dyno[emoji6]

Turbo might stall mate

!Removed! it Clive just keep it dirty & loud [emoji51]
