LCR Exhuast Pipe Diameter

[JamJay]

Hi all, off hand, does anyone know the pipe diameter of the standard LCR exhaust system? Primarily the Cat-Back section but would be good to know the other bits too if anyone knows.

While I am at it, would there be any benfits to removing the OEM centre section and replacing it with a custom made non-resonated section?

I bought a LCR back box and it was bigger than the LC centre pipe and that is 2" so i think the LCR must be about 2.5", also the performance pipes are all 3".

Thanks for the replies .

I think most performance systems (Milltek, Blueflame and I think Piper might only be 2.5") are 2.75" from the cat-back and 3" DP & Cat Bypass/Sports Cat.

So no benefit from doing this at all then, maybe just a bit of noise?
