Seven and a half pounds lighter than the stock exhaust, the hand - crafted Mk6 Jetta TDI Touring Exhaust System replaces the rear muffler and downpipe back, guarantees no Check Engine Light, and offers a 2 - year warranty to underscore AWE's commitment to quality. Fitment Note For TDI owners with DPFEGR Delete systems, this exhaust will only work if your downpipe is designed to mate with the stock TDI downpipe - back system. This is the system for the TDI owner looking to distance the look of their diesel from the masses.
