would this bolt up to my main cat??
 

im wondering if the streetable headers would bolt right up to my main cat or, do I NEED the presilencer to replace the cat?


racingbeat
Streetable Header/Collector
86-92 RX-7 NT
Part Number: 16130

^^^^^^^^^^^^^^^^^^^^^^^^^^^^
come on, I know at least one person has the racingbeat header.

No the racing beat stuff (header or downpipes) will not bolt up to the stock cat.

However with the pre-silencer it will bolt up to the cat back

thanks, now I need to get the header and talk to my friends dad who does welding so I can rig it.:)

does anyone know how much it is off by to fit to the main cat? like too long/short, by how much.
