I'm going to be aquireing a 91 CRX Si soon to race in G-Stock class autox. The car's got a real farty, crush bent exhaust on it now with like a 6" tip. I'd like to replace it with a custom mandrel bent exhaust and was wondering if any of you who were experianced in this had any suggestions as to muffler selection and route. I was considering just doing a dump in front of the axle, but I'm not sure it would be legal for competition. This will be a devoted autox car with some occasional street driving and will be driven to and from the track. Thanks for any help!
