what silicone coupler for a 50 trim w/ a FMIC

[FASTSPOOLINGST]

My new 50 trim has a 2 inch outlet pointing downward, my FMIC has piping that is 2.5 inches. What kind of silicone coupler works the best for the connection between the turbo outlet and the LICP? Right now I have a straight 2.5" piece and it just isn't happening with it. When it does get tight enough to clamp it, it is too wrinkled to get a tight seal. I've narrowed it down to these options, tell me what you guys are running w/ your FMIC's and turbos.
Thanks

1. 45 degree 2.5"

2. 45 degree 2.25 (if it will stretch on to the piping)

3. 2 - 2.5 " straight

Try looking for a 45% transition coupler..That should work. Road Race might have it..

I use a 2 to 2.5" straight transition piece.
