Overview
Get the best sounding, most powerful exhaust for your GT4RS Clubsport. No valves, no muffler, no compromises. You want it LOUD, this is LOUD!!
The GT4RS engine is very sensitive to exhaust length, and our tuned-length 321 stainless Clubsport headers are worth +20 hp and +33 lb-ft at the wheels. They feed straight into the Mega Crack Pipe, which deletes the valves and muffler entirely. Its 3D-printed 347 stainless internals keep the pathways as short as possible while still merging the waveforms of both banks for the full flat six scream.
The headers and the Mega Crack Pipe are designed together and work hand in glove, just like our headers and V11 muffler. The combination makes the same power as the header and V11 system, with the weight and restriction of a muffler taken out.

- Dundon GT4RS Clubsport tuned-length 321 stainless headers
- Mega Crack Pipe with 3D-printed 347 stainless internals
- Your choice of tips: Dundon polished 935-style or Megaphone-style tips in 3D-printed 316 stainless
