Description Leo Vince TT Exhaust for SYM Red Devil / Jet4R / KYMCO Super 8/9. Looking for the ideal ‘street’ exhaust? This is it. The Leo Vince TT hand made offers the ultimate balance between performance, quality and low noise for a performance exhaust. This exhaust is a perfect match for the rider looking to get their stock 50cc going – as well as being a great option for riders looking to install a 70cc cylinder kit, but keep it on the conservative side. As this exhaust offers more back-pressure than a higher end exhaust, it provides excellent off the mark acceleration with fantastic torque – without the engine having to rev its head off. Included with the exhaust is a full fitment kit, ready to install. **Please note, when installing a performance exhaust it is necessary to increase the main jet size in the carburetor. Failure to do this may result in engine damage** Package includes: Leo Vince TT Exhaust Mounting Bracket Mounting Bolts & Spacers Please note that additional recommended tuning items such as Jets, Rollers and Clutch Springs are not included.
