So heres the deal I have a holset turbo w/ a 4.75'' v-band outlet. I currently have a 4'' downpipe on my current turbo that is blown. I havent found a reducer of some sort to weld to the housing so i can use my 4'' v-band on the otherside. Can any body make a 4.75'' reducer to 4''? i would like the transition to be as short as possible so it doesnt take up much room......Thank you.

 

would something like this work? this was for a holeset that was getting a 3" dp.

 

well its a holset h2E, so its externally gated. Im not sure what turbo that is. I just know the turbo has a 4.75'' v-band outlet on it right now and i need it to transition into 4''
