I've used that exhaust paste before. It's not a silicon based product like RTV. I want to say it's called exhaust cement. <br><br>Eric Waterman<br><br><div class="gmail_quote">On Thu, May 14, 2009 at 9:36 AM, <span dir="ltr"><<a href="mailto:wc701lists@bellsouth.net">wc701lists@bellsouth.net</a>></span> wrote:<br>

</div>Like Omer said.... the high-temp copper (colored) silicone works<br>
wonders on problematic exhaust mating surfaces. Use it with a gasket;<br>
or two gaskets if the alignment is poor. Squishable gaskets help<br>
compensate for flanges out of square, etc. Cat' converter heat might be<br>
a little much for it but it still helps. Also, be sure to use metal<br>
gaskets on the cat' not cardboardy ones.<br>
