i bought a 06' Z recently and it had rims and exhaust.
the exhaust i looked up looks similar to an HKS.
the build looks exactly the same and im pretty sure its a knock off
but i just want someone to comment and verify whether it is or not
the ends on the hks are flamed tiped blue but im not sure if it wore away
or if thats even possible
any advice would be appreciated im new to forums and looking to this for advice

 

X02 would be my guess. Definitely not HKS.
Could be a super ebay knock off of a knock off.

 

yea thats what i figured...sounds good as hell tho

 

Blown diff bushing, and deff not an HKS, but still good.

 

what can cause a blown diff bushing and how bad is it for the car?

 

Hard launches, age, bad luck etc etc. Just gets worse and you can possibly break the stud going into the diff cover.

The part you need

 

definetly see that bushing blown glw that, own the xo2 exhaust as well i get compliments every week about the sound of it/ im running nismo short ram nismo copy headers, xo2 cat deletes. ported polished upper lower manifolds. thermal gasket 5/16 spacer.

 

+1 on both observations.. blown diff bushing and X02 exhaust.. i like mine too.
With my test pipes its a bit loud tho.

 

thanks you guys for helping me out..tbh i never would have known what that was...when i was observing exhaust for first time i noticed the black stuff leaking and stuck my finger near it and got a bit of black on my finger....atleast now i know to have it fixed...and thanks for letting me know its an x02...since i bought it like that...ill probably change to a magnaflow...like that sound the best

 

Could see exhaust better if car was on a lift.

 

yea i know i didnt have time...pretty sure its xo2 tho
