ATC70 / TRX70 Stainless Steel Up Lite Series Exhaust

The Lite Series exhaust is a versatile, rider-friendly system built for anyone who wants stainless construction, tunable sound, and strong performance — without stepping up to a full HD system. Despite its lighter construction, this pipe still features a large-exit stainless header that flows well on everything from stock ATC70 engines to highly modified big-bore setups.

The removable-baffle muffler gives you options:
run it quiet for cruising, or pull the baffle for a free-flowing, big-motor-capable tone. Either way, the system delivers clean, usable power and a crisp exhaust note that suits trail bikes, pit bikes, and full-on builds alike.

This is the affordable stainless option — simple, effective, and surprisingly capable.
