I know theres like 500 of these posts already on the forum but what is better E-series or Pro Circuit slip-on pipes? What gives more power,torque?

 

I have a ProCircuit on my 98 Warrior and a FMF on my 89 Warrior. The ProCircuit feels like it has more power, but is really LOUD. The FMF quieter but feels less torque on the low end. Top speeds are nearly the same.

1998 Warrior, Procircuit T-4 exhaust, ProFlo adapter and K&N airfilter (outerwear), 2001 Banshee front shocks, size 12 front sprocket, 6 holes with filters in airbox, Realtor tires on back.

1989 Warrior, UNIfilter with no airbox, 12tooth front sprocket, FMF MegamaxII exhaust, Holeshots all around,amplink, 2000 Banshee shocks on front.

Keep on Rding
