Vibrating since decat

[Guvna!]

Had a decat pipe fitted to my Ph2 172 last week and all is well apart from when I boot it in 1st and 2nd or pull away on a hill.

The car makes a rumbling/grinding noise as if the exhaust is hitting the sub frame?? Thing is there is no play in the exhaust at all.

Any idea what it could be?

need to move the engine forward or backward a bit, i had this shifted the engine forward a few mm and its been fine ever since.

My decat caused this also, tried shifting the engine but didn't help for me. Bought the power flex dogbone bushes and problem solved.

It appears to be getting louder. What do the dogbone bushes do?? Are they expensive?

The dogbone bush is a great device. It's like google. You tell it what you want and it brings it to you.

Much like the SEARCH BAR at the top

Are you still having problems with this ?

Or have you sorted it now ?
