Hi! I want change the exhaust to my Skinny. the configuration is

Manifols -> [CAT] -> [SIlencer] -> [Silencer] -> [Silencer] -> [Silencer]

I think..

Manifols ->[De-Cat] [a little silencer] [straight pipe] -> [end muffler]

What diameter can I use? I want that sounds great but no very noisy

[this is a 145 exhaust] I think this little silencer for retaining out gasses and not lose power at low rpm.



I have a SuperSprint end muffler, I only need change the exhaust outlet but no works on rear bumper hole
