Does anybody know the diameter for the Janspeed exhaust sysyem? If so what is it? Just trying to make sure it will perform well with my engine swap!
Thanks

I can measure later if you'd like?
You interested in the tip size too?
Mainly the diameter for flow purposes but tip size would be good aswell. Its Going on a 2zz with stage 2 cams and rogue wanted to check the diameter to make sure it will flow properly. I haven't got it yet so it's all ifs ands and maybee's! Thanks for your help
