I just ordered an AA N52 Signature Exhaust for my 328i. I heard good reviews about AA and the exhaust in general so I decided to go for it. It was a good price brand new as well for $600.
Just wondering what gains people are getting in terms of hp and torque after installing the AA N52 Exhaust. I know there are graphs but I would prefer personal experiences of the Exhaust and their personal gains.
I also know that there have been many other reviews of the product, but I would just like to get some opinions on the overall product. How bad is the drone? Just overall opinions
