What size fernco pipe should i get for my 99Z. Also, I've heard mixed things about this, is it worth it, and how durable is it?

Thanks for any info.

if you do a search you should find the answers to all of your questions.

 

I have a 3"x3" Fernco. It's a little tougher to get on the TB, but does work just fine.
The 3"x3.5" is the one that fits best, but that is an uncommon size for plumbing so it is rare to find. That's why most folks settle for the 3"x3".
I have had mine for 3 years, no issues. As the tube is on the car longer and heat cycles over time, it gets easier and easier to take on and off. It doesn't get softer, just trained.

The 3x3 is what i had on mine too. Its pretty tough to get on the first time but just like what was said above, it does get "trained". Just go with whichever is available at your local hardware store.
