What Actually Causes The S1 Tizz?

[Rus]

As in the thread title. Since fitting a new rear silencer my car now has a bit of a tizz. It had it a little bit before when the engine was coming down the revs back to idle, but its there when accelerating now at 2500 rpm.

 

Read that some people have put jubilee clips around the flexi section in the downpipe before and this stopped it. Since i've disturbed the flexi is this likely to be whats causing the tizz?

Well my flexi downpipe blew and when I changed it for a new one my tizz noise went away.

It could also be that the exhaust is too close / touching the bodywork around the tailpipes, or the cat's flange hitting the undertray, or the downpipes hitting the air ducts in the undertray. Take the undertray off and have a close look at it for any signs of contact.

I hate it when my undertray makes contact with the cats flange....

Are you sure it,s not the gear change cables on the undertray ?

[Scott_Mac]

Tizz is usually the manifold just catching near the rear bulkhead, however it can also be the cat on undertray and gear cables as said above...

Not as much as the Cat does

I've got tizz and something else horrible at 6000rpm

 

But I have eliminated the undertray rattle...
