I need an exhaust that is:-

1) Light
2) Capable of flowing up to 300bhp
3) Capable of passing UK trackday noise limits (say 100db at 4500rpm usual test)

I've got a Milltek non-res at the moment.

Martellius and J's titanium are of interests. Anyone have any data on these for noise or weight, or any other suggestions?

I may have to custom fabricate as I am thinking I will need more than 60mm diameter...

I would say forget the Martelius even though its 8.4kg i think!

I tested 100db at tickover, never mind any kind of throttle, if you have a manifold its even worse

How about Tegiwa? light, single side, low db
