I've got a guy who will make me a 3" diameter, 0.03 thick CF tube up to 21 inches in length, and is willing to bond flanges on the ends plus reinforce areas for the temp sensor and any bonding points - price is very cheap but I'm not sure if he can make the turn (would need to buy a bend to place between the TB and top of the tube). I'm thinking it's about 22 degrees but I haven't had time to measure yet. Can you measure the length of that Green filter (I'm assuming you got the one with the heat shield and ventura tip) - I'll need to factor that in. Also any pics would be helpful.
