Hi there
only a noob to the Mps scene after only having my gen 1 for 2 months now but after reading about how many people have blown a few stock but mostly modified engines due to the rods I'm pretty happy just leaving mine relatively stock for safety and to save my bank account. Now I'm thinking of going a cat back exhaust either custom or cnt/hks with a 3 Inch diameter so that my car isn't so boring when driving it like a grandmother. Will this modification alter the turbo to spool up earlier and maybe raise boost? I'm just paranoid knowing that mps's are sensetive to mods and that it's bad having these engines spool up early as the high output of torque at low rpm is already hard for the rods as it is. Pretty much asking people with feedback with cat back only mods and if they noticed any changes of boost with this relatively simple modification to the exhaust.
Many thanks guys
