[QUOTE="k-rub, post: 1170995, member: 21298"] So the downpipes with high flow cats and catback exhaust were delivered last week. Initial impressions were everything looks high quality: welds, connections, adapters etc. Downpipes and catback came in two different boxes. Make sure you read the directions in their entirety. It will save you some time if you skip steps. The downpipe box came with a stud removal socket, bolts, clamps, and O2 extension wiring. The original O2 sensor clip is hard to reach from under the truck so the extensions help out greatly. If you get the downpipe kit check the O2 extensions they send you. They sent me the wrong ones. You’ll need ones with 4 pins and they sent me ones with 5 pins. I called SW and they overnighted me a new set of extensions. The catback box comes with everything for installation aside for one factory clamp you will reuse. The downpipe installation was rough and took a while. I’d say ¾ of my time was spent on the downpipes and the rest of the time was installing the rest of the exhaust. I would definitely recommend watching Muredhawk’s video for turbo adapter removal. I bought the stud removal tool he recommended and a butane torch. The studs came out no problem. I also used PB Blaster on all the bolts and had no issue loosening them. [url]http://www.fordraptorforum.com/f261/spd-turbo-adapter-install-easy-way-video-54742/[/url] The truck sounds awesome now! I’ve had multiple neighbors comment how they like the sound. It is pretty loud but not obnoxious loud. Idle sounds like a mini Cummins diesel. Since the exhaust tips are adjustable I initially tucked them more under the bumper. This made exhaust noise seem louder than it should inside the cab because the sound was reverberating underneath the bed. So I pulled out the tips and used exhaust wrap to wrap the pipes from the downpipes back. The difference in sound is incredible. The loud noise inside the cab is gone and I can enjoy the exhaust now. I live in AZ so I really don’t worry about corrosion, but I’ll eventually coat the wrap with silicone sealant. I do go off the beaten path from my local Starbucks so I’ll see how the wrap holds up over time. I have the 5 Star Tune with N Gauge as well. Right now the truck is still throwing codes about the high flow cats. I called 5 Star and they said SW moved the O2 sensor positions. I should have a new tune in the next few days addressing it. EDIT: New tune fixed the codes. There is a noticeable difference in power with the tune and exhaust setup. The shift points and throttle sensitivity is much better than before. And a buddy down the road with a Roush S/C Gen 1 gave it his stamp of approval.
