Quick question about exhaust and car classification rules. The car Im taking delivery of in a week or two comes with a "dual" exhaust, not a true dual. Regardless of looks, Id like to skip the dual exhaust and swap for a single axle-back exhaust, 4 cyl motor so dual is unnecessary. Because its all going to be axle-back modifications and essentially would not gain me anything performance wise, would I be able to retain stock class status? Technically there is the possibility of minor weight savings by not retaining the dual setup but wouldn't that be true of any aftermarket/custom catback or axle-back exhaust swap? Seems like a minor issue and not very likely that anyone locally would protest but I could see the possibility of protest if I decided to enter a national event if there was anything within the rules that prevents me from changing from dual to single.
