SSP-G 2nd Gen GY6 Round Stainless Performance Exhaust

Unlock maximum horsepower and a deep, aggressive exhaust note with the premium SSP-G 2nd Gen Round Stainless Steel Performance Exhaust System . Engineered specifically for GY6-powered 125cc and 150cc 4-stroke scooters, this high-performance aftermarket setup replaces restrictive factory mufflers with a mandrel-bent, high-flow manifold and matching silencer. Constructed entirely from premium-grade stainless steel, it provides exceptional resistance to rust, thermal cracking, and weathering while significantly dropping overall vehicle weight for an improved power-to-weight ratio. Advanced Performance & Engineering Features Premium Stainless Construction: Highly polished stainless steel tubing resists corrosion and handles extreme thermal cycles without losing structural integrity or scaling. Straight-Through Architecture: Minimizes engine backpressure to help your 150cc powerplant breathe more freely, yielding noticeable improvements in top-end speed and acceleration. Removable Acoustic Baffle: Arrives equipped with a removable core baffle, letting you easily dial in your preferred sound signature—from a neighbor-friendly rumble to an open, track-ready roar. Complete Assembly Kit: Includes the stainless header pipe, round muffler canister, heavy-duty mounting straps, and necessary rubber isolation dampeners to absorb road vibrations. Comprehensive Engine Compatibility Index This performance exhaust system is custom-bent to align with standard body frames, utilizing Chinese-manufactured GY6 air-cooled 4-stroke powerplants.

This kit is built strictly for carbureted models with standard right-side exhaust layouts and will NOT fit fuel-injected models without adding an O2 sensor bung. Technical Sizing Specifications Muffler Canister Length: 20 Inches (Overall length) Muffler Outer Diameter: 110mm Round Profile Material Grade: Marine-Grade Stainless Steel Alloy Internal Core Design: Perforated Core with Fiber-Acoustic Packing & Removable Baffle Legal Disclaimer Track Note: This product is intended for track, competition, and closed-course off-road use only. It is not intended for use on public roads, highways, or land where emission compliance laws apply. Mechanic's Installation Pro-Tip: Always change your exhaust gasket whenever you pull or swap headers. Reusing an old, crushed copper header crush washer will lead to persistent exhaust leaks, backfiring on deceleration, and lean running conditions that can scorch your valves. Tuning Advice: Upgrading to a high-flow exhaust system changes your engine's air-to-fuel ratio. To maximize your gains and prevent lean engine bogging, we highly recommend up-jetting your carburetor main jet by 2 to 5 sizes and tuning your CVT roller weights to match the updated power band.
