standard silencer... how restrictive??

[Oil-burner]

I did it in stages so cant really tell you over standard
But yeah its deffo better.
I personally wouldnt go 100% straight through again if im honest, its too noisy for a daily.
Infact i keep looking to go back to a modded standard system over my stainless tbh.
I loved it at first but it gets boring quickly. Although that might just be me getting old!
