Honestly man, there are and always will be a million and a half threads on "which exhaust combo" or "which intake" should someone get... Its all in preference, and everybody will have a different one. Sound clips online will help, but you never know how accurate the sound will be.
I have the Dinan, its perfect for me. 05ZHPCPE has the UUC, he loves that... You'll never get the same answer twice my friend...
