i want to say 3x3... Not 100% sure though. I tried this one time and didnt have alot of luck getting it to fit. Some say its easy and worth it some say its hard on the lid and might crack it. If end up doing it i will find a more flexable type of rubber to use.

That coupler is known to crack lids, as soon as you put either a aftermarket (90mm TB on, you go back to accordian coupling anyways).

Its great for looks and that is about it.

I picked up a smooth bellow for $25 shipped from the classifieds, check there for a good deal

You can get knock off SLP bellows on ebay for about 25 bucks. I like my fernco, it was cheap and hasn't damaged my lid. It should be a 3x3.

Based on what I have seen from your mods you probably wont, start making 400+ and thats when they show up, its a fact. Be aware.

Fernco is junk. You can get silicone hose on the internet for >$20 that fits better, works better and actually looks good.
