Difference in performance or sound? The difference from dumps to tailpipes is huge. I had dumps origionally, couldn't hear **** inside the car. Put on tailpipes and the sound was a HUGE difference inside the car. Outside the car it was a noticeable difference but the main difference was from inside. I'm back to dumps now though I just love it
I had tails then put dumps on loved it ever since but I do kinda miss the look of the chrome tailpipes. You will notice a difference in sound but not really in performance.
YEa i kinda forgot to specify that I personally think it sounds better outside of the car with dumps. I got dumps that extend a bit further back than the dumps I had origionally.. That helped the not being able to hear in the car and also kept the sound I love. There's nothing like driving by a car and setting off it alarm because the dumps make the ground shake (Sorry i'm kinda drunk right now)
