what is the Hp gain? do you reccomend this if you already have the q60 red sport?
- Michael
Hi Michael, they haven't been rated for a specific power gain, it's mostly about sound, and they are still going to be louder than the stock Red Sport exhaust.
Does this part void the warranty? I'm looking for suttle increase increase in sound. Similar to the stock oem sound of a 2011 G37 coupe. I was told that this change could cause the car to not pass the emissions test. The car I have is a 2017 Q60 sport coupe.

Since these are after the catalytic converters, they will not void any warranty, or impact emissions.
