   Hi, i have a SS Race Centre Section to a Ashley 3 Inch Backbox, i watched a video yesterday with the exact same setup with standard CAT and for some reason it sounded very Raspy, also when i drive slow and change gear the exhaust creeks like fuuuuke, could this do with anything that the centre pipe hasnt been put on right or the nuts and bolts arent tight enough?.

   Probably your engine moving a lot when you rev it - normally can be sorted by fitting a harder lower gearbox bush/mount:

   it's the lower engine bush I think - £28

   The springs are there to help keep the join in contact when the engine moves, causing the exhaust to pivot on the join.
   
   If they are noisy then you either need to try and grease them up, or minimize the engine movement.

    What I did was I put grease onto the springs and this fixed the creaking noise you get.

    Meaning the springs on the joint where the centre pipe connects to the cat?.

    Sorted the problem out lads and lasses, the bolts up front werent tight enough so tightened them up and also fitted cable ties to the hangers on the exhaust for that bit of support, no more creeks and for some reason the exhaust has got raspy, i think it was blowing up front because the joints wernt tight enough.
