Pretty sure i have one in my tool box i will throw it in. Thanks

 

While you're in there I'd replace the main with a 72.

 

The old Propipe is a good one, if it gets a little too raspy, the packing in the rear section of the baffle gets blown out, repack it and it will calm down. A simple hose clamp blocking off holes on the baffle can change back pressure. Very friendly pipe to work with and the roar is it's own

 

It definately has a unique sound but i really like it. And when i bought the pipe i did some searching here and came across the thread about blocking off holes. I have one row blocked off and that seems to make my low to midrange feel a little better.

 

The Propipe I have had the long baffle when purchased and too much back pressure. Bought a competition baffle which is basically straight thru, had to weld a washer on the inlet to get some back pressure
