AWE Tuning S4 Downpipes

• 3" at turbo, 2.5" diameter (63.5mm)
• Add 20+ hp
• Part of the complete A.W.E. Tuning S-Flo system
• Manufactured in-house for excellent fit and finish
• Our downpipes have set the standard in the industry

This direct fit replacement for the stock downpipes consists of 2.5" diameter (63.5mm) T304 stainless steel downpipes (they taper from 3" to a real 2.5"), 400 cell per square inch catalytic converters (DOT/EPA approved), CNC cut flanges and brackets, and Aeroquip flex joints. Also available are offroad use only test pipes to replace the catalytic converters. All welds are TIG welded and finished (all of the internal welds are smooth, where it matters most) and the all the bends are mandrel. The much larger diameter tubing with eliminated pre-cats results in immediate turbo spool-up and big power at high rpms.

Many hours were spent to ensure that our downpipes will fit your S4 with absolutely no interference problems. Since the average downpipe install can take over 8 hours, this is not a product that you want to take chances on regarding fitment.

Please note when ordering: since each set of downpipes are handbuilt, you cannot order test pipes separately from the downpipes. They are a matched set.
