Hi Chaps,

I was in the group buy last September of the Larini (Club Sport for an S2)exhausts, but ever since the exhaust has been on it's had a vibration (more of a tizz) which is not there when cold but when the car has warmed up it is there. Around about 3000 revs it's particulary noticable. I tried looking all over myself but found nothing (grills, heatshield etc). I recently had my S2 MOT'd (which it passed with flying colours ...whohhhhho!) The guy at the garage said he'd had it on ramps and tested it at different revs and found no touching or vibrating heatshields etc??

Now I have phoned Larini and they are happy to test it for me (so this is not a bitch at them at all). Although David did think it may be the flexi pipe as they are suposedly not very good on S2's?... Can anyone tell me if the flexi pipes are a commonn fault? The question I wanted to ask... Has anyone else had this problem with vibration and had to have there exhausts tested?? Or had to have them replaced?

Regards,

Mac

It is probably a heat shield.

How much is a flexi-pipe and where do you get it from?

Also do you need to replace the gaskets too?

I managed to get a second hand one, only 6K on it for 50 squids. However, if I was in the same position now, I'd buy the Stainless steel one that either Eliseparts, elise-shop or hangar 111 has - can't remember who it is, but one of them does it for about £150 all in. Get the SS gasket and bolt set too, £16.

I noticed that the standard flexi section looks restrictive on the inlet and outlet sides (pipework diameter reduces). I am betting the welds aren't the best either. Is the aftermarket SS one any different?

I think mine may 'Tiz' at approx 4k rpm but it's not something that really annoys so I've not investigated it.

Would prefer if it didn't obviously...
