Whats the deal with magna flow?I think theyre awfull ,raspy as heck when you get into em,like an old school glasspacks and waay overpriced..ive had alot of different mufflers and magnaflows were the worst.maybe its my setup with f/i and headers size pipes etc,too each theyre own but i dont like a raspy exhaust.Im sure the setup makes a difference and on stock probly wont sound the way mine did.FWIW i like the dynomax ,welded case straight thrus.deep sound stay the same throughout rpm range.Magnas from what i heard was quiet at idle,and raspy throughout rpm range.Maybe dual 2.5s with headers and f/i isnt breating enough through them.If you decide to get magnas ,Ive got 2 like new 2.5 in 2.5 out,ill give ya a deal on,still shiny new.Good luck.
