I have a question about the Injen exhaust... From what i remember, there is a new and older version where they did modifications to the H pipe or something to reduce the drone right? If not, can anyone please tell me what modifications they did? I tried emailing Injen but they replied saying there isn't any modifications made (WTF)...

And also, how would i be able to tell if i have the newer or older version?

 

Show me a picture and i will tell u

Angled mufflers and tips = old, angled mufflers but straight tips = newer, burnt tips + H-pipe = newest.
