I recently finished installing a Procharger M-1 on my 502 for a HTM i was wondering if putting a set of headers would help out much or if there are any other upgrades i should do allong with the Pro charger. I am new to the performance boating and trying to learn as i go. Any input would be greatly appreciated.
not sure on a good match.. but keep in mind the noise law..
good luck
If you don't have it already you will definitely have to invest in some external steering. For power, the 502 didn't have the best manifolds for power, but they were ok. A set of headers will help, but the question is where is enough. They will cost between $1500-3500 depending on what headers you go with and you will probably gain 10-15h.p. It is your call, but I would be happy with the stock manifolds.
Good exhaust can't hurt, are you using a carb or fuel injection?
