Akra is pretty quet but you'll need a tune to get rid of the start-up rumble. It's pretty loud. Some have said it lacks soul up top, and I get what they're saying because it doesn't howl and rumble like a race exhaust does up top. It's plenty good, but I'm withing I used a stainless 200cpi X-pipe instead of the EVO X-pipe.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
