Whats wrong with the GDi exhaust, thought they were one of the best.....too noisey? BTW....urs a 54 plate 172?
A mate of mine, Turner, has the GDi system. He mentioned the growth of the tail pipe when it got hot.
My Prospeed moved around like f**k. Was incorrectly mounted, so when hot was actually pulled towards the bumper, melting the 182 surround. It also fell to bits.
Bought the GDI/Piper effort. Sounds better, built better and not restrictive.
