i have a 73 nova with a 383 stroker. what do you think would be a good exhaust size for my car? i was going to go with 2 1/4" flowmaster kit. what do you think? also what about emissions legal exhaust, what would be good for that? i guess since i am on the subject, anyone from nevada that would beable to give me some advice on emissions control for smogging my car? I am in the sparks area. i built my engine the month after i had just smogged it and i need to smog it next month. i am afraid it will not pass.
