Question What size silicone for stock TB

I need a silicone reducer for a 98 ss stock T/B to a 3" pipe I mesure just short of 3 3/4" on the tb, should I get the 3.00 to 3.75 ID x 3 in. long or 3.00 to 4.00 ID x 3 in. long

Was it a nice fit or was it a little loose . I have the silicone elbow that you have in you sig pic 4" I want to go a difrrent rought , but I tryied it just to test fit it and its a bit loose but I think a clamp would work to keep it tight . I would just think it should be snug without the clamp though .

How much boost are you making ?

A 3.75 would be a bitch to get on there. I did it when my TB was stock but I had to heat the hose up to fit it on there. A t bolt clamp would hold it just fine. Oh and to ron z28 I copied your charge pipe Ideal but I put to 45 degree angles and a hump hose. All from siliconeintakes.com

Yeah even the 4" was snug on my FAST 78mm. I used a 4" to 3.5" transition.
