Type R and SIR piping
What is the stock exhaust piping size on a type R from japan I heard it is 2 1/2 but ive also heard its a bit smaller . Its actually in mm and they round it off to 2 1/2 in inches and also what is the j-spec gsr's (SIR) exhaust piping size?

Re: Type R and SIR piping (disordeR)
The actual piping size is 60.5mm which is 2.38" and yes the SiVTEC/SiR uses the same size piping size, in fact the mugen/spoon/HKS/M-Silent headers which supposedly have 2.5" collector are all actually 2.38" (60.5mm) so i suppose that the Dc JDM 4-1 is the same as its supposed to be a replica of the honda ITR manifold
