All he would have to tell you is either the unit was installed poorly or how much he hates it due to the install. These units hold up to HIGH Hp all day long. The cobalt is now EVO and so far I don't see any of the EVO guys breaking or bending the units they have? SO in all being said it seems to be install and user error on most. ***For the owners concerned that they may have bent the brackets or dampers, contact grant@ingallseng.com for warranty or questions. Ingalls has a way of testing units and the damper will show sings of improper adjustment or install. For all kits that weren't an issue Ingalls will replace units deemed to be defective.
