Squeak from RSR

[captainmark]

I upgraded my 993 with a set of RSR's from Gert about two weeks ago. Loving the new sound but it's coincided with a new, persistent and highly irritating squeak. Sounds like it's coming from rear right and the only thing that's changed is the new exhaust so I guess the noise is coming from there...

I didn't fit it (got the local garage to fit according to instructions in PCGB Tech Articles). However should they have used any grease/lube anywhere (ie on heatshields clamp etc)?

Many thanks in advance
