Hi guys, need some advice, ive put new dffuser on car with fins ( its the st one with cutout) and i have a piper cat back, now the exhaust is not sitting flush in the cut out of the diffuser its hanging a good three inch lower why is this? do all pipers hang low?

Get some photos up, would really help. My piper is hanging and leaning a bit towards the centre. I believe that's an issue with the hangings as a member mentioned to me this evening.

and its spitting out loads of hair like material what the hell is that?????

^^

its weird cant be knackered already surely

when you got your back box fitted was this before or after the rear diffuser was put on?

Mechy should of align it up correctly to the hole, mine took a while getting it flush.

The hair like material, which i believe to be fibre glass which is like hair, this is from your silencer/muffler, it's a sure sign that the exhaust inside has corroded and soon needs to be replaced.

If you don't replace it there is a chance deadening material will block the exhaust and cause a loss of power as more back pressure and fumes will build up.

Worst case Scenario

its not even old its brand new more a less about three weeks old

i can't remember correctly now if the st has a silence before the cat back, if you have a silencer on the piper cat back it could be faulty if you have the standard ST silencer there is a chance it may be that.

i suspect the new piper cat back you have brought is faulty, badly put together as you shouldn't have any fibre glass coming out at all.

i'd notify the seller, there is a possibility that whats coming out is excess padding that has been left in the cotainer that hasn't been stuck down.

it will be hanging low if you have a pre facellift and its a facelift exhaust

What this lot said. Get it sorted or it could effect how your engine runs and could knacker it!

im phoning them tmoz to see if they will replace the backbox they should, if not im screwed ill have to get a full new system which i dont want to shell out for when its there fault its bust

oh well looks like im going to need a new back box as the current one is knackered, lasted a month haha so yeah everything else is ok, just need to replace the back box

If you've had it only a month id be on the blower to them saying its under warranty and needs to be replaced!

yeah i will in the morning just checking to see if its the back box that needs reaplacing, am i right in thinking that mate yeah? im shocked its broke already tbh

new backbox on its way
