I am trying to get a Hydeout ready to fly this season and need a header and pipe for a Webra 145AAR. I think I will need a 1 1/2 inch rise. Don't know about the length. Any ideas? Thanks for yalls help in advance. John

The OS header will also fit the Webra 145 & 160.
For a carbon pipe, try ES from Central Hobbies or the Aeroslave pipe. Aeroslave shows length data for their pipe.
You can get a metal Greive pipe from Piedmont.
