I have a greddy FMIC Kit that needs a new reducer on the hot pipe side. So it needs to be 60mm to 50mm. My question is this: 50mm is about 2 inches, but 60mm is 2.39 inches. So what would be better, go with a 2.25 inch coupler or a 2.5 inch coupler? Reasons? Also, where are the best places to get them online? I only know of slowboyracing.com and siliconintakes.com.

Probably the smaller cause Im sure the sylicone couple will stretch .10 of an inch. going bigger requires you mash the couple down with clamps which can cause leaks, cracks, or pipe blowing off easy.
