Default 90mm TB and Maf connecton?

I was using a Fernco connector for the TB and Maf on my old setup but now its a 90mm and wanted to see what everyone else was using.

The OD of my stock 75mm is the same as the stock LS2 90mm OD - 3.850". What you have should work.

If you want a silicone coupler, here's one place that sells them:

I have plate behind the TB for my Nitro Dave 90mm kit. I used the SLP smooth bellow and cut it to fit. (85mm Maf and NW 90mm TB)

I tried a silicone coupler but the alignment between the maf and the TB is so far off, it wasn't possible. Expanded the stock bellow opening with boiling water and it works great with a 90mm UMI and an 85mm MAF.
