The new DP is super awesome!! That really woke that car up even from the Stage 1. The front tires are worthless now and the traction control is hyperactive if left on. The sounds that the car makes now are really cool also. The spool and the DV are really audible if your foot is in it, but you can barely notice its there driving normally. The cast pipe is much less tingy than the sheet metal mandrel bent styles. It is much louder during a cold start even with the factory cat back! Absolutely NO regrets! Thanks Achtuning!
