Inliners International Forums General Discussion Hi Performance Lost torque by bigger pipes?

We build a new exhaust setup for the 235 (typical dual Offy/holley-weber/split exhaust/m4F/ .06 over).

The pipes are 2 1/4 inch diameter with 2 flowmasters just before the rearend.

I was kind of disapointed when I drove it the first time. It feels like it lost all of the low end torque.

Is it possible to loose so much torque just by installling bigger diameter pipes? I thought that the lower backpressure the better it is.

Thanks, Frank
