Title: CMNSL exhaust - should I be worried ?
Post by: SPR on June 05, 2020, 04:59:52 PM: Afternoon

Had my new exhausts fitted for a few hundred miles and when cleaning have noticed that there is a bit of weld missing which is allowing a small leak where the header meets the silencer.

I realise that this is a small thing - should I be worried as to the longevity of the exhaust etc ?

I've raised a support ticket

Thanks

TBH - that is my thoughts as well

Let's hope that CMSNL agree to send a replacement.

Nothing like the quality of the welding on the 500 pipes, those are as close to perfect as you can get.

I gather you didn't replace them all as the lower pipe looks to have some gravel rash or is it a reflection of the floor?
That’s a reflection .... they have all been replaced

I would suspect so ... I went with cmnsl as the exchange at the time made them cheaper - I may rue that decision :(

Post by: bobv7 on June 06, 2020, 12:03:36 AM: I suspect they come from exactly the same supplier and so who sells them is irrelevant!

Post by: paulbaker1954 on June 06, 2020, 08:49:41 AM: I was very pleased with my CMS units and I think they use same supplier as DS anyway.

When I had a potential problem with one pipe after 2 years they replaced it no question and even paid carriage both ways

Great service

That sounds great - lets hope I'm as lucky :)

Just heard from a rather nice chap at CMSNL who says they will dispatch a replacement :)

Fingers crossed
