AUDI A3 S3 8V CATTED DOWNPIPE - AWD

Take your Audi A3 8V to the next level of tuning with the ARM A3 8V Catted Downpipe. The OEM downpipe is restrictive and won't safely support more than a basic Stage 1 tune — the ARM unit relieves the turbo of excess back-pressure so you can flash Stage 2 maps and beyond. The result: faster turbo spool, more power and torque, and an improved exhaust note.

Highlights

• Gains of up to 20 awhp / 27 awtq.
• Faster turbo spool and an improved exhaust note.

Construction

• TIG-welded T304 stainless steel, built to last the life of the car.
• Three sections (upper, midpipe, adapter) joined by precision-machined V-band connections for a secure, leak-free fit.
• Laser-cut mounting bracket and CNC-machined prongs match the stock mounting points.
• Stainless flex section reduces turbo stress from torsion under hard driving.
• 200-cell high-flow catalyst in the OEM position — reduces fumes and CEL risk, with no O2 extension wires needed (does not guarantee no CEL).
• Includes a reducer for stock slip-joint exhausts and a straight 3" section for 3" catbacks.
