The A4 has returned for a new exhaust. He requested we reuse his existing mufflers. Some pics of the car when it came in.



leaky welds



sweet muffler delete



infamous crush bend



muffler and previous welds



All off !



Now time to begin. We wire wheeled the existing Audi factory flange and reused for a good factory seal.



Started with welding a bend to the factory flange then that to a 2.5" to 3" transition.





quick weld pic



Here is the front downpipe section



working a little further added a flex pipe for minimal exhaust movement.



We then flanged and installed the front section and started on the new mid pipe



also tig'd in the hangers



Pic of the routing through exhaust tunnel



We flanged the mid pipe right before the rear axle. Next we had to make a smooth transition for the dual 2.5" section. This is what we came up with.





Now time to hang the existing mufflers starting with drivers side



then completing passenger side





Thanks for looking !
