SMOOTH TRANSITIONS FOR G-SPORT CATALYTIC CORES — 2.500" TUBING TO 4.000" BODY
GESi's universal Transition Cones create a smooth, flow-friendly transition between a G-Sport catalytic core and the rest of your exhaust system. This cone adapts any 4.000" OD body G-Sport core to 2.500" exhaust tubing, matching the taper G-Sport uses on its factory-assembled converters.
Sold individually — a core needs one cone on each end, so order two per core (or one, where the core mates directly to a merge or flange on the other side).
FEATURES
- Factory-matched taper — the same transition geometry G-Sport uses on its weld-ready converters
- Stainless steel construction to match the core and survive exhaust heat
- No sensor fitting — clean cone; add one of our O2 sensor bungs wherever your sensor needs to sit
- Weld-in installation for a permanent, leak-free joint
