Muffler Bypass Exhaust
#16
I installed these about 1 month back. A bit louder than I expected but I am well truly used to it now. So much so I think I would struggle going back to the stocks....
I've also managed several police passes without them even looking up so it is completely possible to keep the decibels down when needed.

Just to clarify, are we talking about the complete muffler bypass (like the cup cars), or something like the gundo hack which modifies the muffler by adding a piece of pipe between the two ends?

Peter, mine (in the video clip) is just modified or the Gundo Hack. A complete bypass I hear is extremely loud. I've heard the cup cars out at Miller and they are super loud even at lower rpms. Hope this helps.

Can anyone tell me if a flash tune will be able to gain back the loss of low end torque? Also, with a fabspeed intake, stock filter, modified exhaust /// if I do an ECU what kind of gains can I expect. I certainly don't want to lose any more low rpm power, but I hear better mpg, and gains starting at 4,000 rpms. Thoughts?
With increased flow, and the increased intake, I would expect that I already have some HP increase? Amounts? Perhaps 10HP total. With an ECU upgrade would I get another 10 with increased mpg? I'm running 92 non ethanol and adding Amsoil octane boost that gives me another 2.5 ...so about 94.5 octane in every tank.
Thanks for any insight on this.
