Cadillac CTS-V - 90 degree elbow silicone adapter reducer

So my Volant tube is basically 3.75" OD.....

And my NW TB is 4.25" OD......

So can I stretch a 4" to 3.5" reducer over these? Or will I have to get a 4.5" to 4" reducer? Would that even work since I'd have to clamp them down really good? I'm having a hard time finding half sized reducers.

Ok I'm a f'n idiot......my Volant tube has the 90' degree in it.....I just need a straight reducer.

closest thing i could find

I wonder if you gould throw your volant tube in the oven for a bit and gently expand the diameter of it just enough to take up the slack from the 4" reducer.

Look here:

They have just about every size you would need.

Can I stretch a 4" to 3.5" reducer over these? Or will I have to get a 4.5" to 4" reducer that will be 1/4" too big?

Order one of each, one 1/4 too big on each end and one 1/4 too small on each end

Not the worst idea ever, thanks boss.....just trying to avoid wasting money is all.
