anyone know if theres anyone that sells a 4" down pipe that will work with a kb-racing hotpipe set with a cxracing 76mm turbo? i know there are alot of duramax stuff i just done know if they will fit? if i can find one for a decent price i can have a shop in town do it. if not ill have to take it outa town. if not anyone know about how much i could get one built? no one in my town will touch anything over 3" thanks for the help guys. trucks a 2004 gmc sierra z71 ext cab with a 5.3 lm7

all ive found so far but idk if it would work?

 

I doubt the diesel DP will fit. Why not ask KB to make you another one? That way you know it will fit. Any why 4" with that turbo?

 

the turbo i got has a 4" exhaust housing i currently have a 4"-3.5" reducer and it bolts up to the turbo and the down pipe, but if u go that route the down pipe needs redone. so im thinking of getting a 4" down pipe and doing the reducer into the mid pipe by the frame? i sent KB a message i was jw if theres anything out there some one is using that would work? thanks for the help man.

 

Just buy a 4'' v band clamp and female flange, 180° and 90° mandrel bends and like 3' of straight pipe. Pretty easy to make it yourself. You can do it with a Porta band, grinder and 110 welder. Materials will be right around $100 or so. Mandrel-bends.com for the bends and pipe and rps for the flange and band

 

I'll put this here too, as I did in the email. A .96 a/r housing from them will pretty much solve all you problems and make everything bolt up. Probably flows about the same since it will be an open housing versed the devided 1.15.

 

thanks for the replys guys. ill see what i can come up with.
