Have done a search but no success, just wondering what sports cat or de-cats are people running with the blitz nur spec R system? I really wanted to run a 3" sports cat but I'm struggling as the 3" nur centre section tapers to a 2.5" where it meets the cat down pipe. Ideas would be appreciated and thanks in advance 👍🏻

 

I've got and RCM sports cat downpipe with an RCM resonated centre section then the Blitz Nur spec backbox all of which are 3", I'm not sure if the flanges have been altered as I bought it like that

 

Yeah I'm thinking I may have to go down the route of changing the centre section for a 3" too so I don't have to mess about! Thanks for your info 👍🏻

 

If you do make sure it's gonna work with the blitz backbox as you may end up having to chop and rotate a flange some where

 

That's some good advice, thanks
