We have several customers out there with systems that see frequent track use and lots of heat cycling with no issues. My personal E92 has an IPE system with over 20K miles and a few track events with zero issues. Either way, the systems themselves are far from garbage or I wouldn't have one on my car.
Maybe a bit hyperbolic to say 'garbage' but Ive had Akra Evo and for the price IPE is, its nowhere the quality of the Akra and shouldnt be anywhere close to that price especially since its not made of exotic material either.
