I have K&N cold air and magnaflow 16707.. Nice tone with city driving.. kinda throaty on the highway.. I've been told at stoplights it sounds great.. Otherwise if you wanna do the cheaper route, find a muffler shop that will install 2 1/2 from the axle back.. Its the Y pipe you need bigger then just choose the mufflers you want.. You'll be pleased either way.. Post some pics of it..
