#72 of 78 Higher flow muffler, Toyota Highlander Hybrid, improve MPG??
Jun 10, 2008 (12:46 pm)
What I have: 2006 Toyota Highlander Hybrid with front wheel drive, 3.3 liter 6 cylinder as found in many Highlanders.
Would a higher flow exhaust system, for example a Flowmaster muffler series 50 or 60 help, in addition to removing the twists and turns in a Highlander's exhaust system ? I have not found any catback systems for Highlanders. Would I really have to replace the catalytic converter, too? Or how would I know if the stock catalytic converter impedes exhaust gas flow? I also assume there are EPA regulations on catalytic converter replacements, too.

I am looking for any feedback on after market muffler systems, like Speedtech or others. I have visited two different websites for two different manufacturers which include video/audio bytes of the products as installed and driven. Any dos or don'ts or advice? Performance and sound seem to be the "plus"
