Thanks for help. Although i do not have the npp exhaust i wish i did. Lol
I talked with guys at vengance and they said hanger are the same but rear tip outlet need to be adjusted because they are different. So i hope to buy the exhaust and just have shop adjust tips to fit rear valnce. Price is crazy that i can get for this cat back. Which is why i want to do it instead of even a legato axle back.
