Saw it on another thread and thought it was well deserving of it's own, being that there are so many pipe inquiries lately.

Joey Tamez (JT) is now making custom pipes domestically. I have used his pipes in the past and they are top notch.

Here is his website: https://rcjetpipes.com/

I am not affiliated with his business, he is just a good friend and an incredible modeler/pilot. This new line of exhaust pipes suits his product line very well.

Give it a try!
