<div dir="ltr"><span style="font-size:12.8px">Yesterday I took a look at the empi header to the right HE pipe . I removed the clamp and was able to check the HE OD and it was 35 mm . I could only pull the header back 3/16'" . I was not in the frame of mind with the excessive heat we have here to remove the header . What I did was pull the header back the 3/16" insert a block of wood to hold it there and tried to insert the .011" aluminum sheet I have . Since the header end was sort of oval shaped I really could not get even one wrap of aluminum sheet in there. What I ended up doing was using the permatex ultra copper gasket maker and getting it in the header gap and rotated the crush seal to spread it around the header and filed the header flange so the clamp would fit better. Then once I felt the Permatex was in there enough and put the clamp back in place and found the metal ring was not seating well and backed off the clamp and forced the ring to fit well then tightened the clamp. I let it sit now over 24 hours and have not started the car yet. My hope is it will seal the leak and if not I'll remove the header . I just didn't want to mess up the seal on the left since it does not leak. The empi header flange on the right was not formed right as far as I can tell . It's the header not the HE pipe . Now that the permatex is at least sealing the crush ring to the header flange and the metal ring now sits against the crush seal hopefully this will fix it at least until I can either replace the system with something better or see what I can do with the empi cheapo header removed . If the sealer blows out which I sort of doubt it will then I'll see what I can do. I just can't handle the noise the leak makes . </span><div><span style="font-size:12.8px"><br></span></div><div><span style="font-size:12.8px">I used a small screw driver to get the metal ring up against the mesh crush ring/seal because it was only hitting at best half the crush ring . I got it to contact all the way around so it's even now. I even took a 1/4" square metal bar stock I had to try the beat the empi header so called cone lip so it was more of a inside cone shape the filed the outer edge to a bevel so the clamp would not stop against it. Did this before filing or adding sealer . I think the main issue was both the sealing surface of the header and the metal ring not seating fully around the mesh crush ring which is all this sort of clamp/seal system does . The crush ring does fit snug on the HE pipe. </span></div><div><span style="font-size:12.8px"><br></span></div><div><span style="font-size:12.8px">Well drove the car last night and today, NO more exhaust leaks . I can't say if it was fixing the header flare and getting the metal ring to seat better or if the permatex sealer helped .</span><div class="gmail-yj6qo gmail-ajU" style="margin:2px 0px 0px;font-size:12.8px"><div id="gmail-:121" class="gmail-ajR" tabindex="0"><img class="gmail-ajT" src="https://ssl.gstatic.com/ui/v1/icons/mail/images/cleardot.gif"></div><div id="gmail-:121" class="gmail-ajR" tabindex="0">William</div></div><div class="gmail-yj6qo gmail-ajU" style="margin:2px 0px 0px;font-size:12.8px"><div id="gmail-:11t" class="gmail-ajR" tabindex="0"><img class="gmail-ajT" src="https://ssl.gstatic.com/ui/v1/icons/mail/images/cleardot.gif"></div></div></div></div><div id="DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2"><br>
