Muffler & Gas Mileage
Hey, I just bought my Firebird Formula yesterday the previous owner took off everything after the Y-Pipe. People have told me that the fact that I dont have a muffler is confusing the engine computer causing it to dump more fuel resulting in less fuel efficiency. It sounds believable but I'm wondering if its true? . By the way I just ordered a new hooker catback system
Thanks guys!
BTW go take a look shes bone stock except the muffler but still beautiful
