KLINE INNOVATION

Replacement of the stock 600cpsi catalysts, with either high flow HJS cores, or de-cat pipes, opens up the sound significantly, as well as drastically improving turbo spool for increased power, and reduced spool time. This coupled with the twin 70mm dual oversized down pipes, and 89mm oversized center section, as well as flow optimized pipe free of compressions, allows the engine to reach its full potential. An additional laser cut aluminium cross member is included with the exhaust, to allow for the oversized center pipe.

The rear silencer section, working with the cars stock electronic actuated valve system, we crafted a set of light weight, valvetronic rear silencers. on valve open the system becomes completely freeflow, for optimum performance, and aggressive sound. under valve closure, exhaust gases are diverted through a series of chambers and acoustic filled section, tuned towards low rpm torque, and a very quiet volume at cruising speeds.

The rear section is finished off with a set of quad carbon fiber tails, manufactured in house from pre-preg F1 grade carbon fiber, with inlaid branding.

Great product for the $$$$
This edger is awesome. Easy to put together. Intuitive. I put it together inside of 10 minutes. Shifted the edger "guide" down, and went to work. This corded electric model is WAYYY cheaper than the battery powered (or gas powered) models, and is absolutely up to the task. Lightweight and maneuverable. Quiet. Easy to store. The motor got a little "bound" when I tried to edge too fast, but the manual had clearly warned me on this - to back up, let the blade get back up to speed, and then edge again. The lawn edges are now straight, well-defined, and immaculate.

Great but could be Epic
If you’re looking for a solid edger for sidewalks and driveways, this is a great tool. It’s powerful, well-built, easy to assemble, and simple to use. For edging, I would definitely recommend it. However, I wouldn’t recommend it as a true trencher. I bought it for both purposes but mainly needed it for trenching. The maximum cutting depth is only about 1.5 inches, which isn’t deep enough for most garden borders or running cable. In my opinion, a real trencher should be able to reach at least 3 inches deep. The limitation comes down to the blade size and guard design. WORX could improve this model with a larger blade guard and additional wheel depth settings. If they released a version capable of 3–3.25 inch trenching depth, it would really stand out in the market. Overall, it’s an excellent edger, just not a true trencher.

Works Great!
Much quieter than I was expecting. Lawn had needed this for years, I regained 6"-10" of driveway/sidewalk back. Makes the rest of the neighborhood look bad LOL Only the cleaning up wore me out, but it should be much easier next time.

Very light and effective trimmer
Style: 20V String Trimmer Kit
I’m very well designed trimmer that cuts through grass and weeds very easily. The battery lasts about 45 minutes. It’s fairly light and easy to use. I think it’s also a pretty good value.
