If I was looking to DIY replace my current cat-back system with another, what parts should I be replacing? And are there recommendations / trusted items for this?

What I have so far:

Gaskets?

Spring bolts?

Should I be using an exhaust sealant instead of / in addition to replacing the gaskets?

Probably worth getting some new exhaust hangers as well mate, the old ones may have perished over time.

I did mine a few months ago and only used gaskets and hangers. It was degraded to hell though so need some cutting and redrilling for new bolts

Thanks, that's a good idea. Where did you source yoir hangers and gaskets from? Are they particular to the 300zx?

 

I just bought some generic eBay specials mate and they seemed to do the job ok! Time will tell how long they last but no rattles or knocking, and more importantly, complaints from my mechanic when we had to remove it the other day for access to the Hicas! I posted photos when I did mine on my members post about my car on this forum if it’s of any use?
