Default 3" centre section to 2.5" downpipe

Currently have a scoobyworld sportscat 2.5" downpipe with a 2.5" 2nd cat decat and scorpion 2.5" centre section.

Recently got hold of a 3" toyosport cat back exhaust system. Do you think it would mate up ok ?? Id assume aslong as the flanges on both were same, it should be ok with a 3" gasket??

I know cars like these are fussy with needing remaps, would it require one just changing the centre pipe and back box??

Thanks

Hi there

Yes you will need tweak at least for backbox,centre section if you will replace both of them

If they fit on yours 2.5",without the 3"->2.5" adapter(I think Scoobyworld selling one adapter) I don't think will fit

may see if I can just fit the backbox on for now, would of thought they'd mate up ok if I got a 3" gasket and both flanges are same size, would just be a step down in diameter between backbox and centre section, but could be wrong, may pop to local exhaust place see what they think, or try it out anyway
