As much as i probably never will, what exhaust do you like and how much power do you think it adds? I do agree with you.
Well Flowmaster if you like loudness, that's my personal pick. But if you want a nice tone go with Magnaflow, Borla, or MBRP. Or if you really want to spend money, Roush. And it doesn't add all that much, well depending on what kind of system you get. A few extra ponies is about it, nothing really noticeable. But definitely better flow than stock, a better sound, an slightly more efficient (minimally noticeable though).
Yes it would and a tune is the best way to get more power of any mod except for forced induction.
That's fine, everyone has their own preferences, just making suggestions. But the 5.0 does sound pretty good even with the stock exhaust.
I appreciate and value your suggestions too. Thanks.
