You guys with the cheap exhaust connections just drive me nuts!
I was cheaper over-all, and a substantially higher quality product, when I just bought my entire exhaust, headers to the muffler, from BC Broncos. I can't remember if it was $700 or $800 total, but it was the best exhaust decision I've made.
I started out with a set of ceramic coated long tubes, that I paid $150 for, and then I bought an exhaust system from LBC (or whatever) for $250 or $275, plus shipping. Then I took all of that to a nit wit at Meineke, who charged me $300 to weld it up, and did such a shitty job, I had to take it home & fix it myself. That's about $700 total, and I was only working with 1.5" headers, and 2.25" tubing, and turd mufflers.
Clearly, I had to do things twice to learn the lesson. Save your money, go BC Broncos.
