It's been a few years since I had a new exhaust installed on my car, but I also changed my single exhaust to duals on a 57 Plymouth with a 318. The guy doing the installation was/is also an old car nut and maybe was a little more picky than the average Joe, but it was less than $200 from the exhaust manifolds back and they're lasting just fine. I drive my cars on a regular basis and it sure helps when it comes to keeping the mechanicals in shape. Dan C Spanaway, WA |
