I'm looking into buying new a new exhaust header for my 87 NA, i already have a Bönez Dual Cat converter and i was looking into racing beat headers, but on the racing beat website it says the header is made to fit to the racing beat presilencer. So my question is, A) will the racing beat header/presilencer fit onto my bonez cat converter?
B) Are there any other exhaust headers anyone would recommend?
C) How much will this increase the power and how much louder will the exhaust be?

Thanks for the help

 

A) The bonez main high flow cat replacement will fit with the Racing Beat header only if you have a custom connecting pipe (look in the archives there's a thread on it I believe) or if you have a custom catback.
B) Racing Beat or SDJ are quality
C) Definitely louder, power increase is questionable depending on who you talk to.


EDIT
Something similar to this
