New Exhaust
 

Thought of trying this out on my 85 GS. Feel free to give input. Its my first rotary so dont know how this would sound or perform.

4.5" Tip / 2.5" Inlet / 18.5" Length

Will be connected to a custom 2.5 exhaust setup wih possibly a rb header.

Will not last. Needs stainless steel packing inside, from Racingbeat/Magnaflow/Borla.

Also, 2.5 is too big for NA, but good for a mild turbo.

^To add on to his statement, the 2,5 inch is too big for stock ported NA engines. I'd imagine it would use up that much exhaust and then some for big port work.

Still yet, it won't last.
