Well ya know? I have used Ken's muffler for years now after my surgery. It's been a blessing knowing my wife's car is taken care of and I know it's guaranteed. You guys are great . Thanks to Kendall , Chris , Scott and all the professional techs you have. My vehicle's range from 1977 to 2008 2wd and 4wd and all have been taken care of with A-1 service. Brian
