Exhaust Rattle with New Midpipe and Test Pipes?

SunnyDays

Hi,

Posting this on behalf of a friend who has just had some exhaust work done.
He currently has the following setup:

Berk Test Pipes
Custom X pipe and mid pipe with resonators
Nismo Axle Back

After install between 2k and 3k RPM it is rattling, it sounds awful / broken

It did not do this before, when running Berk Test Pipes, stock exhaust, and Nismo Axle Back

Any ideas on what the problem could be here?

Thanks

Loosen the flanges, arrange the piping so it doesn't hit anything to cause rattles, carefully tighten flanges.

^^^ What he said. If that doesn’t work, it’s possible something is loose in your resonators. Also, on my 350z I had a rattle without any contact between the car and the exhaust. I just loosened everything up, shook it around, tightened it down again and it went away. Good luck.
