I wanted the pipes welded in instead of clamped.If you don't trust your shop to remove the resonators why would you trust them with your car at all? This is one of the easiest mods you can do. Just measure, cut, and clamp. I am not a mechanic by any means and I did it in my garage on jack stands without fail.
Hit me up if you do, I would love to see your Shelby. I was fortunate enough to drive one for most of a day before I left SE Michigan and it was an amazing experience.Looked it up and they get good reviews. It's 40-45 min away. Might end up cruising out that way.
