GAS B9/B9.5 RS4/RS5 EA839 2.9T Downpipe Set

If you're ready to go Stage 2 or just looking for a more aggressive sound from your 2.9T RS4/RS5, look no further.

Our 3.5" stainless downpipes are hand-built here in Canada to our exacting standards, ensuring maximum performance and sound with all the reliability you've come to expect from GAS. Both versions feature CFD-optimized transitions, full stainless construction and perfect OEM fitment with both stock and aftermarket exhaust systems!

Features:

• 4.5" turbo outlets tapering to a smooth 3.5" diameter all the way to the midpipes for maximum turbo response, faster spool and lower EGTs
• Full 304 stainless construction, TIG welded & back-purged for longevity
• Hand crafted in Canada, not overseas
• Billet flanges ensure a precise fit every time with no leaks
• EPA compliant high-flow cats rated up to 1700bhp total
• GAS lifetime warranty

Proper tuning is recommended for both options. Running catless downpipes without a tune will result in a check engine light!

Includes:

• GAS downpipe set
• Downpipe gaskets
• All required hardware

Fitment:

• 2018+ B9/B9.5 (8W) RS4 2.9T
