Anyone get any crap from their subaru dealer beacuse of an aftermarket exhaust?? I asked mine if it would void my powertrain warrnaty and they said..."Yes because they cause excessive backpressure". I just said ok because I did not want to waste my time trying to explain the principle of free flowing exhaust system to an idiot. Isn't that some crap. Im going to call SOA to get the skinny on it.
