On some parts there seems to be a pretty big difference in price. Is there a big difference in quality?

Years ago I bought a H pipe for one of my cars from Year One. It fit perfect and is still on the car to this day. That said... I have bought a lot of pipe from Accurate as well. I had a problem with a muffler when it was very young and they told me to send it back but I just welded it up. I've had my share of pipes rust out too but I guess that is the environment they live in.

Interested in your experiences.
