What is the difference between a 940 turbo vs non-turbo exhaust? I mistakenly ordered the non-turbo exhaust for my car.

 

It will not do for your turbo car. So you will have to return that.

 

Ordered a new set. Took my time installing it and the 30 return period was up. Anyone want a non-turbo exhaust+cat for cheap?

 

pretty sure you'll need to be more specific than just 'non-turbo exhaust'. I think there's a couple variants depending on the year, and EGR vs no EGR. does this include the downpipe, or just cat and back ?

 

Why dont you call them and explain things even if 30 days have gone by. They are not always impossible to reason with. You may not get a refund but they could give you a gift voucher and you could buy something else from their shop. Its been happened to me a couple of times with refunds.You just got to smile,be kind and friendly and explain. Say you bought another correct exhaust from a nearby stores.
