performance manifolds and muffler on a 63 impala
I just got a 63 impala and i want to make it a cruiser, so i want to get the best gas milage possible. ITs a 283 and i was thinking about replacing the stock manifolds for some performance ones to improve flow. Also, what would be a good, relatively cheap muffler with a nice deep semi agresive sound that also has good flow? any recommondations?
thanks guys
