i was wondering if i would get the same power out of a apexi n1 compared to the RB muffler? and would the 13b from a fc fit into my 81?? im relaly planning to do this later down the line with my car

 

The muffler isn't really where the majority of the power is; the header and lack of major flow impediments is the important part. I doubt you'd see much difference between one high flow sport muffler and another one, at least not for a stockport streetcar.

The answer to your second question is yes.

 

oh okie kool so would i get the most power by haveing the RB header to a straight pipe then a muffler??

 

Yes you will max high-end horsepower that way.. and Cerritos PD on your butt faster too!

 

haha cool yeah cerritos cops are a bitch whatevers though ill be happy with my car when i get this **** done ! whooo!!!
