Default NW 102 to 4" tubing

What do ya'll do to transition from the NW 102 to 4"tubing? The NW is 4.25 OD. I can't seem to find a 4.25 to 4.00 coupling...

LC, my 4” adaptor stretched over my NW 102. It’s tough, but it will go. Best and smoothest transition you’ll get.

Would it help to put it in hot water a bit to soften it up to fit? Not sure the material in question softens up this way.

Thanks guys.


98, I didn't see a 4.25" in that list. Not sure if being 1/4" bigger is any better than being 1/4" smaller -guess it would depend on the material.


Scott, remember what material you used?


Yep, I think hot water could only help. Almost every material expands with heat...

I have the 4" from that site on my car with my fast 102 TB.

Was not bad at all getting it to fit. I just stretched mine over.

Have you measured the diameter of the Fast TB? Just curious if the OD is just as big as a NW...
