you cant go wrong with any of the 3 companies..as for myself i decided to go with ARH because i have tried all other companies on different vehicles and liked ARH the most...installation takes a long time but i had access to a vehicle lifter which made it a bit easier for me but even with a lifter it took me about 8 hours to have them installed.consider getting a catback aswell i have the non-catted version hooked to the factory catback and it sounds horrible but the performance gains are really worth it , i have noticed some engine heat temperature drop IMO its a pricey mid but worth every penny
I currently have a magnaflow magnapack so I'm covered on that side.
Thanks everybody for your input now I just have to pony up the money for it.
