Re: Hardin Marine - Cyclone Shorty Header
 

I have sold many sets of these. Yes they are a direct bolt on header to replace the Gil's and work great! Most of the applications are lower Horsepower 500-625 HP N/A

Re: Hardin Marine - Cyclone Shorty Header
 

The Cyclone Shorty is a great product, but if you have higher horsepower needs take a look at both the Typhoon Series and Hurricane Series of stainless headers. We build systems for a variety of different applications, just give one of our techs a call to help determine what is best for your particular situation.

Any Idea how much the Typhoon headers would help a 620 HP 502?
