Larini exhaust - getting louder!

[ryallm]

I know a lot of peple here bought Larini exhausts in a couple of group buys, so I wonder how other 111R/S2 Exige owners are getting on with their zausts. After less than a thousand miles, I am convinced my Larini is getting louder, especially after a track day I did yesterday. I am starting to wonder if some of the sound deadening material in the can has either melted or been blown out. Noise is such a subjective thing it could be my ears are deceiving me, but on anything other than a totally steady throttle it really is bloody loud now - much more so than I remember it being when I first fitted it. Conventional wisom is that some sports exhausts quieten down a little in the first 1000 miles as they soot up so it is a bit surprising. Anyone experienced anything similar to me?

It also depends what kind of matterial they have used in the exhaust, but indeed some get louder by blowing little pieces matterial out...specialy when you high rev a lot and the gasflow is fast, I've had such experiences too with some BMW M exhaust... for me a good thing because they could use some more sound, but when you have already a stage 2 that loud like some lotus cars have, its not that fine!
When I was at Wiesmann Germany in 2005(also was there a few weeks ago) and I talked about the "soft" sound of the demostrater car, he said it will get louder in time because little parts of that material will get blow out the pipe, and ofcorse they could give it more sound to start with because they build their exhaust stainles steel themselfs...

The 111R/Exige2 seem to be particularly ferocious in the amount of heat generated and then contained inside the rear bay. The Cat and the comprehensive heat-shielding give the std baffled silencer a hard time. Having removed several std silencers, you can hear/feel the fried absorbent material rattling around inside the can. Any exhaust manufacturer using the std 'E' Glass packing is in trouble (like they care )

yep, but that material you are using is different stuf...how is that holding? and I guess you can use much smaller diameter cans/exhaust mufflers, so less matterial is lighter weight is good for all cars

It is an amazing material Rene. I took apart one of the trial silencers - half-filled S2G, half-filled E Glass. The E Glass came out in lumps! Only ever seen this on the Elises/Exiges.

Thanks for the replies everyone. I will see how the Larini stands up to the several track days I will be doing over the next few months. If it continues to get louder I will be having a wee word with the guys at Larini. I can see myself coming your way for another zaust at some stage in the future Jim.

Ah - Mark! Didn't realise it was you till I checked your profile. Jamie'll keep you right!
