Boxster S noise, please help!

[brit911]

Hello most helpful forum

I've just bought a 2000 Boxster 3.2S manual. The car has done 82000 miles, has 2 issues which I think are related, there is what sounds like an exhaust blow. I have checked the exhaust and cannot find one! Years ago I worked to GM and the V6 engines has EGR issues with a pipe that would split and sound like a blow? Does the S have this?

Also the idle is rough.

The car has a tequipment exhaust and the last owner put new headers & a new alternator recently. The car drives & performs well.

Any and all help appreciated.

I got a S 3.2 3 weeks ago. Although my idle is rough sometime (working on fixing things) there is no blow on mine.

There are those that know more than I but any exhaust problem will affect the O2 sensors. You have any codes or CEL on?

Hi, no lights on and engine runs very smooth..

You just said the idle was rough.

The idle only is a little rough, smooth as silk the rest of the time

If you cover the tailpipe with something (not your hand), you can then sometimes tell if you have an exhaust leak by listening for it...
