Exhaust centre pipe mb3

Question

Hey guys,

 

Recently bought a japspeed 4-2-1 manifold for my mb3 (https://www.japspeed.co.uk/honda-civic-4-2-1-d-series-tubular-manifold.html) which said was a direct bolt on fitment to original standard/aftermarket cat/decat. Now I know on my civic the cat was in the manifold but I assumed the bore of the cat would be the same as the rest of the exhaust system (standard).

 

It isn't. Bore of japspeed is 2" and I believe standard is 1.5"/1.75" as it's not a proper fit. I can fit it so it's not blowing but the rattling is hella annoying.

 

Is there a 2" bore centre pipe and backbox (would assume the backbox would need to be the same size as centre pipe) that I can buy relatively cheap? I've tried looking but can only find stuff like m2 motorsport. Is an mb6 standard pipe 2" bore? Just asking because there's a couple of cheap ones on ebay.

 

I would at some point change the rest of the exhaust system but want to fix/do other more important things first! (timing belt, handbrakes cables, etc)
