I am building a down pipe for my car and we are using a gt47 turbo on it. The exhaust outlet is 5" off the turbo, but id like to use a 4" downpipe. Does anyone make a 304 stainless reducer for something like this?

Also, where is a decent place to buy v-band flanges for the downpipe and intercooler piping?

Thanks
Ryan

 

Ryan,

We stock them, how many do you need?

 

Why not just use a 5" downpipe and make more power?

Global tech engineering has 5" mandrel bends for a good price

 

There just isnt room to get a 5" piped down past the cross memeber, and 4" will be plenty big enough imo. Im just looking for one transition, shoot me a PM with a price for it.

Thanks
Ryan

 

you can make a 5x4 reducer using a pipe fitters blue book.you should be able to find a blue book at any welding supply store.it will give you the demensions for the arms of your reducer.its super easy
