I read lots that by increasing the flow of the exhaust I can run into overboost problems and the possibility of losing power .I also have the CAPA edit (latest I re-map I think) and use the generic 10psi map, have a bigger cooler also (same as wog cooler). Dyno'd @ 6 psi got 225rwkw a while back before I got the cooler and latest re-map (sent edit box back to CAPA for latest maps). Im guessing I'd have around 250rwkw now as the car goes heaps harder than when originally on the dyno.Anyway.. My question is..Is there a possibitlity that I can still run into overboost problems if I remove/replace the stock cat? And im also thinking of replacing the stock rear muffler with a Genie Turbo 3" in 3" out muffler?? (my best mate owns an exhaust and suspension workshop, so all this costs me nothing).Any help would be great, as im still trying to get my head around the mechanics of this car..
