Unresonated xpipe vibration

[S54 Schnauzer]

Hey everyone,

Just installed a SG unresonated x pipe and right when it starts up, goes from a stop 0-1K rpm has a very loud vibration (inside the cabin) but then goes away from 1.5k onwards. Is this normal?

Thanks.

No vibration noise is normal lol. But double check everything like positioning and mounting. Believe it or not also check your sections one pipes and ensure its not hitting the trans cross member. Can always add back the old piping.
