SuperTrapp Stout 4" Slip-Ons are brewed to perfection! They quench the thirst of riders longing for beautifully, crafted, 4" slip-ons with a pleasant tone and unsurpassed performance gains.
- These larger bodies are brewed to perfection.
- These non-disc-based, massive 4" slip-ons allow riders to make a bold statement with their newly developed core.
- The streamlined, internal tapered, billet aluminum end cap with recessed fasteners comes pre-installed and is a sign of the true craftsmanship that went into the design of these pipes.
- The newly shaped inlets flow better into the O.E.M. head pipe as well as SuperTrapp True Dual Head Pipes (sold separately).
- Stouts are now available in black as well - black ceramic bodies with a black, ceramic-coated, contrast cut end cap.
- Black and chrome optional replacement end caps are available and sold separately.
- SuperTrapp Stouts are SAE-J2825 sound compliant.
- SuperTrapp Stouts are compatible with SuperTrapp True Duals.
- Notes: Optional cores are available for certain models at an additional cost. The SuperTrapp Stouts' tapered core is minimally louder than stock for 2010 and newer FLH / FLT models. SuperTrapp Stout Slip-Ons provide a heavy, broad spread power curve right from idle with a 9.3 (16%) HP and 10.5 (14%) torque gain over stock (measured on a stock 2010 FLH). At 95.6 dB ? 2,000 RPM, or 2.4dB over stock. Sound test data on 2010 and up model-specific slip-ons was achieved using the O.E.M. CAT-equipped headpipe. Use of these mufflers on headpipe with the CAT removed or True Duals will result in substantially louder results.
