As winter approaches, having a reliable exhaust system for your 1997 4Runner is more important than ever.

I found it to be especially effective at reducing drone while providing that deep, powerful exhaust note. Trust me, if you want a long-lasting, performance-enhancing glass muffler, the Thrush 24203 is a top pick.
