I hear ya. I seem to recall doing the same, but can't remember what vehicle...
I remember that the 1st gen Tacoma engine specs, and you might know this, were rated higher than these 3rd gen 4Runners. Some have postulated it was due to our more restrictive muffler. If so, you might have liberated a little extra power...
Yea now I know, measure first order second haha... Hmm that’s a possibility, not sure though. We looked in my oem muffler and it definitely looked pretty restricted. The butt dyno felt a horsepower or two in gains.
