DG Pipe specs

[Viper79]

Hi, Can anyone tell me the tail pipe diameter on a DG pipe to suite a RM 400 N/T
The standard pipe is a Inch and a quarter o/d in US specs.
Im thinking of getting a DG pipe but I will need to try and match a universal silencer to fit it.

Regards

1 1/4 inch universal fits nice om RM400N/T. No spring loop though. You can expand the 1 1/8 one easy enough as well.
Cheers,
