With the help of YouTube, I have successfully convinced my mom that the best solution to her ghetto-sounding rattly muffler is to just straight pipe it. Just the muffler.
Now I've studied all the fun stuff about exhaust back pressure and flow velocity, and I know the muffler (and whole exhaust) is tuned to get just the right amount of restriction to facilitate gas flow, like putting your finger over the hose.
So, if we replaced the muffler with a pipe a few steps smaller than the rest of the system, would that retain the same amount of backpressure and keep the low end torque?
