Lethal offload X: I just installed this on my 12 Gt500. It comes nicely shipped and the bend and weld quality is good. I did the install by myself in my garage with the front tires on a couple of harbor freight ramps. The biggest challenge was the space limitations. I barely fit under my car sliding around on my back and I'm a skinny guy. This would have been a lot easier on a lift. Everything is straight forward for the install though. The O2 sensor on the passenger side is extremely difficult to access. It was impossible for me to get my hand up the connector to disconnect it because it is basically between the firewall and the engine. Luckily I had a 7/8 O2 sensor socket that I was able to get on there once I had the downpipe unbolted from the exhaust manifold. It was also the tightest thing I have ever wrenched on. It took everything I had to break it loose with a 12" long 3/8 ratchet. I about had a hernia over it. You will also need a long extension, about 12 inches, and a deep 15mm socket. She sounds good on startup now and I want to say I can here the supercharger wine a bit on startup too. Very happy with the product. Review by Gary / (Posted on 4/5/2013)
