Try Ah Spares for the down pipe, which is mostly to accommodate engine rocking without the exhaust system cracking. You can also bring the car to a good muffler shop that does custom fabricating and have them weld in a section of woven stainless flex pipe like the kind used on todays cars for the same reason. Had that on two Healeys so far and it’s muc more robust than the standard flex pipe. <br><br><br><div class="yahoo-signature"><a style="font-size:12px" href="https://apps.apple.com/us/app/aol-news-email-weather-video/id646100661">Sent from the all new AOL app for iOS</a><br></div><br><p class="yahoo-quoted-begin" style="font-size: 15px; color: rgb(132, 115, 255); padding-top: 15px; margin-top: 0px;">On Wednesday, September 18, 2024, 11:45 PM, Bob Spidell via Healeys <healeys@autox.team.net> wrote:</p><blockquote class="iosymail"><div dir="ltr">Listers,<br></div><div dir="ltr"><br></div><div dir="ltr">The exhaust downpipes for both 4- and 6-cyl cars have a section of <br></div><div dir="ltr">flexible tubing before the connection to the muffler.
