Chaps, I am looking for a bit of expert guidance here. I have a XR2i track car and need to upgrade the exhaust system in the coming weeks.

Since it already has the Ashley 4-1 manifold, it seems sensible to go for the same brand. But no-one at Ashley or the specialist retailers can tell me if it will pass the stringent noise tests on track days.

Does anyone have the system/know of a mate with one that may have tracked their car? Or better still, anyone know the DB's the 3" tail system would be pumping out?

Cheers,
