Separated Gases DP Leak
#1

Hey everyone,
I purchased my Miata used with a T25 turbo kit already in it. I've noticed that the separated gases downpipe is leaking at the joint in the picture, however, the joint on my downpipe that I circled is actually further up where the arrow is pointing.
Anyway, just wondering if I should have this joint welded to stop the leak or if it's un-welded for a reason. I have searched to no avail. I appreciated any help.

<p>It is a slip joint to allow for differential expansion between the main pipe and the waste gate pipe. Main pipe has constant flow of hot exhaust, waste pipe has intermittent flow. So you should not weld it, or one of the pipes will develope a crack </p><p>Other vendors use a flex joint in the waste tube. Some use a double slip joint, which are reputed not to leak. </p><p> </p>
