THE OG TC
Open-cone stainless-steel 2-1 race exhaust for Twin Cam Touring models
The OG TC brings SQ1’s open-cone race-pipe formula to Twin Cam Touring bikes. Stepped stainless-steel primaries and the signature Guppy Collector are designed to maintain exhaust velocity, reduce reversion, and support peak performance.
It is loud, unrestricted, and built for riders who put performance first.
