reeceybeaney Posted December 20, 2018 Share Posted December 20, 2018 Not sure where to start! Have had Motordyne ART Pipes fitted for nearly a year now and they have been the best aftermarket mod I have ever purchased... However... Driving along today and all of a sudden the exhaust tone massive depends and loudens significantly. It sounds as if the exhaust has literally fallen off! I pulled over to see that the silencer of the pipe is no more than an inch above the floor a careful, but noisy, drive home to jack the car up as quick as possible in the dark... ...Only to find that the silencer pipe has nearly completely come away from the main part of the exhaust pipe, revealing a huge hole! My presumption is that the weld has failed resulting in a crack. Just wanted to share my experience with these and hopefully nobody has this problem, I believe the art pipes may have been updated in previous years and I may have an old batch! The later image is borrowed from another forum, however the hole in my exhaust is about the size of the drawn orange circle around the welded circumference!

Jack94 Posted December 21, 2018 Share Posted December 21, 2018 (edited) Holy s**t, bit more than a small crack then! How old are these pipes? And how's the other side holding up? Edited December 21, 2018 by Jack94 Quote Link to comment Share on other sites More sharing options...

And how's the other side holding up? Yeah not much of a crack Well I'm guessing they're the oldest versions of the art pipes because the newer ones look slightly different on the ends of the chambers! Other side looks fine Quote Link to comment Share on other sites More sharing options...

It looks like they've been tampered with before, look at the weld in the O2 sensors bung, that's not a Motordyne weld. Current shape looks like in this set: https://www.torqen.uk/nissan/350z/exhausts/test-pipes/45-350z-de-motordyne-advanced-resonance-tuning-art-test-pipes-md-002.html Quote Link to comment Share on other sites More sharing options...

I've read American 350z forums and the Motordyne guy on there has said they added that bracket/revision for this reason I'm well aware they are a slightly older model but still shocked they would fail like this!

Mark@Abbey m/s Posted December 21, 2018 Share Posted December 21, 2018 The weld hasn't failed it has cracked around the outer circumference of the weld. Looks like vibration has caused the failure. I would just repair and add a brace between the resonator and the main pipe 2 Quote Link to comment Share on other sites More sharing options...

nissanman312 Posted December 21, 2018 Share Posted December 21, 2018 (edited) Is that just a silencer looking at that wouldn't be hard to make a set of those with a set of de cats Glad it's sorted Edited December 21, 2018 by nissanman312 1 1 Quote Link to comment Share on other sites More sharing options...
