Yea, I thought that too when first researching cutouts. So I went with Badlandz HPE cutouts instead. Chose that brand because it had the highest reviews, and lowest complaints about leaking or failed motors. (as compared to QTP, Granatelli, DHP)
Had to pay someone $300 to weld them in.
After 3.5 years, ended up replacing both motors, one of them twice. The reason was the carbon buildup around the butterfly valve (see pic below). The "standard" cutout motor just isn't strong enough or beefy enough to power through the carbon buildup.
Between the cost of the replacement motors, and the new gaskets required every time you remove the exhaust to change the motors...I quickly spent more than what the NoWeeds would have cost me initially.
So, I swallowed my pride and bought the NoWeeds. Absolutely loved them! 3.5 years later, when I took the sidepipes off my old Challenger to sell it, they had some carbon buildup, but were operating flawlessly.
Had I bought them in the first place, would have actually saved some money. Plus, the owner of NoWeeds was great to work with; he customized my order a bit to make it more compatible with my sidepipes setup.
