If you are going for sound I would stick with the short tails or other axleback. If you are going for performance, don't spend the $250 on straight piping and keep the CNT but get test pipes or HFC's.. Itll beef up the CNT exhaust a ton, but you will keep the gains from the exhaust.
A member on here got 326whp/268tq from CNT Exhaust, TP's, & CAI
