2004 Audi A4 Exhaust Reviews

2 reviews
Fit perfectly - right length, flange bolts lined up correctly, etc. I would suggest ordering a few other things when replacing the intermediate pipe: 1) flange for this intermediate pipe (Ansa® HW7005); 2) flange for the catalytic converter; 3) a new coupler exhaust clamp like this one: https://www.carid.com/hooker/hooker-clamps-and-hangers-139245597.html. I had to remove the intermediate exhaust through the engine bay by disconnecting the catalytic converter and intermediate pipe together from the engine. Once out, then I disconnected the intermediate pipe from the cat. Mine required grinding off the rusted bolts.
