Whatup. Im looking to buy exhaust for my car and im debating between the HKS Hi-Power True Dual or the Nismo. Just because i hear the HKS is really good but i was wondering if it takes away from the sound it has stock because i think stock sounds pretty nice. So i was wondering if having the nismo keeps the sound and emphasizs it a little but not enough for it to be noticeable because i want to be able to tell the difference. Or does the HKS sound better and or more powerful.
Comments and Help Greatly Apprciated. Thanks

 

Go to a 350Z meet, and listen before buying.

Besides, the designs are completely different. Which design do you prefer?
