active zaust on v8 project

[WabTheKing]

ive just picked up this active exhaust from an s4 4.2 v8

what advantages does this have over a non active exhaust?

basicly is it worth me chopping it to fit the coupe? or would it be a pretty pointless exercise?

cheers

The active exhaust as I understand it is to reduce noise at part throttles, the second route opens to allow greater flow as theback pressure increases. If you want to rumble through town centres seting car alarms off and scaring old ladies, this isn't for you!

Wab, Are you getting old?

You are building a V8 can then want to quieten it down....

106db with a turbo engine, gonna be even worse with a non turbo!

most track limits are 99db and as its a track car - that makes it pretty useless!

was just going to use the back boxes with the actuators to pass noise tests then when its actually under load all hell can break loose!!

sounds like a good plan, now that you have the exhaust it prob wont harm fitting it in.

Is there any likelihood that this system increases torque in the NA engine at lower revs? I think it might! Problem is, does the extra weight negate any gains made?
