I'm attempting to put hard pipes on with the stock CT26 and I'm having a hard time finding a place locally that has the silicon coupler from the turbo to the piping and before I order it online I want to make sure I have the right size... So that's my question what is the right size for the turbo side of the coupler? I'm guessing 2.25 but again I want to be 100% sure before I purchase it.

Ct26 used a 2.25 coupler
All piping connections are 2.25 except throttle body
I believe it a 2.5

Don't buy the cheap 5 dollar ebay couplers ...they rip easily and don't do well with heat and a little oil
A nice 5 ply coupler will last a god while and from my experience hold up well with under hood temps

I used a 2.75" silicone coupler from the 3000 pipe to the throttle body, which was tight, but fits well.

The Speedsource lower IC pipe that I used with the CT26 was 2". I highly recommend that you use a ruler and measure. The 2" coupler was super-tight, but fit.

Exactly why I asked, because when I measured mine the OD shows as 2 1/8, so I figured I would ask to see what the community is doing. I didn't know if basically stretching a 2" over the extra 1/8 would be better or tightening the 2.25" over the extra 1/8 would work better. Looks like it's 6 of 1 or a half dozen the other...
