Look into RAWTEK. they make the best intake through exhaust tip for the tdi, I loved mine, couple it with a Malone stg2 tune and your in business :thumbsup: if you have the DSG, you will want a tune on it as well to run the Malone stg2. I went with a HPA stg2 DSG tune and was thrilled with the results of the three together, rawtek Malone HPA. Be aware, IT'S AN EXPENSIVE ROAD TO TRAVEL, if you decide to do it. Otherwise a straight pipe might be just as good for sound, and it's practically free in comparison.
