I have read about people disagreeing and debating if they are worth buying. I have shorty headers, stock cats, magnaflow y, 3" single pipe, magnaflow 14" muffler split out to dual 2.5". Will these help my bottom end at all or give it a more aggressive tone? Also my downpipes are 2.25", would increasing them to 2.5" or 3" help?
