What sized piping should I get for a 38mm tial wastegate dumptube? Would 1.5" work or would I need 1.625"?

Thanks in advance.

 

i don't know if that extra 1/8" is going to do anything...i think that most people use the 1.5"

 

wasnt sure what size to get since i don't do the welding. anyone esle?

 

The outlet of the wastegate should be approximately 1.5". At least mine is. You probably won't see any benefit from going larger.

 

i was just gettin ready to search this.

thanks for the replies and letting me leach

 

thanks everyone

 

yup,i always use 1.5" for those wastegates.if you want to go bigger,2" is what i use,but really no benefit unless for some reason the pipe will be VERY long.

i only need the pipe to go from right above the exhaust ports on the head pointing straight down to the ground

 

would one u bend be sufficient or should i get one u bend and like 6" of straignt pipe?

every time i've bought 1.5" bends,they come in a "J" shape with one very long leg.usually that long leg is more than enough length.

i'm just waiting for adam to get the parts i need up on the website. he offers u bends in 1.5" aluminized.

 

home depot got some mandrel bends that ranges from 1" to 1 3/4" for $3-5

 

1.5" diameter dump pipes sound like crap to me. I like to step mine to up to 1.75 and then 2" for the last 3rd. 1.5" will work prefectly fine though.

its galvy'd conduit pipe....ive used it also...works alright just a bitch to weld w/o any pinholes...im redoing it this winter w/ aluminized piping

 

i'm just going to get a bend of aluminized 1.5". might as well do it the right way the 1st time.
