The TurboWorks downpipe is made of stainless steel.
Diameter DP 2.5 "(63mm)
Final reduction to 57mm standard exhaust
100mm middle silencers
The last element of the exhaust has a constriction that adjusts the downpipe to the standard exhaust.
After cutting off this element and connecting it with a larger exhaust, we get the full diameter over the entire length.
