Custom made 304 stainless steel tig welded catless downpipes.
By far the most cost effective upgrade for any turbocharged car.
. OE style turbo flanges
. 20-30 HP increase with tune
. High flow race catless construction
Paired with a quality exhaust system, the sound from the N54 with these downpipes is incredible.
