Super Jet Pro tec vs sizzler?

[Fstrkls1]

I'm looking into getting a pipe for my sj650 I know it's all about the b pipe but it's not in the budget. What is going to give me a harder hitting Bottem end the pro tec m1? Or the Coffman sizzler? I'm running a Riva head with 35cc domes in it, water box delet, stock carb, and stock nozzle? And soon to be 9/15 hooker
What do think?

First off all put your watetbox back in.... and run the sizzler

X2 on the waterbox. Run inline 3/8' ball valves on your lines to the sizzler pipe to adjust pipe temp and it will rip.
