I was looking to get the dual Evo2 Exhaust system for my V6 Accord Sedan but I've been getting feedback that it only fits the coupe, is this right?

I was also looking into Unorthrodox Racing Pulleys but they only offer underdrive pulley for my car, no accessory pulleys. How should I go about balancing all 3 pulleys?

My last concern is Tein Coilovers... there is only a Basic coilover set available for the sedan and coupe, but the SS set is only available for the coupe... does this make sense?

Please enlighten me...
