November 5, 20241 yr My 2006 Honda FR-V, 2.0l petrol has failed MOT with an exhaust leak, co content exceeding limits and lambda outside limits. My mechanic has pointed to the centre silencer, which is leaking at the joint with the rear section of the exhaust. Four years ago, I replaced the exhaust center silencer box with a pattern brand (EuroFlo) - I can't remember if as the OEM spare part was even available at that time. Is it normal for this component to wear out so quickly? I'm still using the original OEM exhaust for the rear section and that has lasted for 18 years and 100,000 miles without issues, whereas the replacement has failed after just four years. The EuroFlo part is still available, though the cost has doubled since I last purchased it and I'm probably not going to see much spare change from £300 to get it done, plus I have to source it myself as the mechanic says his suppliers are unable to obtain it. As far as I'm aware there's no other option here, any thoughts?
November 5, 20241 yr Unfortunately, aftermarket parts don't always last the distance like original parts. Can it be welded as this may be sufficient to keep it going as long as there are no leaks
November 5, 20241 yr Author I'm not sure, my mechanic didn't suggest welding it. I could ask him. He did mention that it looked corroded, and he said something about the replacement gasket not being as big as the OEM one which may have contributed to corrosion, not sure if I understand what he meant by that i.e. why the size of the gasket would impact corrosion. But I look at it myself - only he looked at it.
November 7, 20241 yr I'm sure if there is corrosion around the area as long as it hasn't gone too deep then possibly it could be taken apart, cleaned up and a new gasket with sealant fitted
