New Z owner in need of new Ypipe and other exhaust parts.

[LC350z]

Recently had a service and my exhaust at present time is a full Scorpion catback.

 

Was told my Y sections flex pipe are in rough condition and need fixing or replacing. 

Was told it would be better looking at a new Ypipe although currently got scorpion ones unsure what to do.

 

Also my back box tips are uneven and too close to bumper so it's melting it abit.

They said to look at a full cat back japspeed system as the labour and materials cost would be similar to purchase and labour of the Japspeed K4?

 

I feel like that would be a downgrade as all reviews about Japspeed seem to be bad sound and quality especially with a HFC that I need to replace shortly.
