T350 track day silencers?

[sanquin]

Has anyone tried T350 track day silencers? For instance http://www.actproducts.co.uk/shop/silencing-trackd... ? How much noise do they take off?

I am planning to go to the TVRCC Continental Meeting at Zolder and there is a rather strict 95 dB limit there.

Yes I use them for the T350 but I have only ever attended 105db track days. In my experience all places come up with different readings but I think they take off around 7-10db.

It depends what exhaust you are running to start with but they should bring you under 105 but maybe not 95 if your running a sports exhaust of some kind. I think if you used them together with the standard exhaust then thats your best chance of being 95 or under as I've been tested at under 100 with the standard exhaust only.

Ok thanks, I think I will order them.

Took mine down from 103dBA ish (or 106 if you believe castle combe!) to 98 at Goodwood.

Easy to fit and effective.

Which ones did you order and how much as i have the same exhaust as yourself, and have been looking for a while.

I ordered 2 x 4", it worked out about £80 each including shipping, VAT etc.

Very happy with them and simple to whip on/off for the trip home.
