Patriot VS TTI VS Dougs

I just installed a Summit 2.5" exhaust system on my Doug's headers. Quite possibly the easiest exhaust install I've ever done. I used the Doug's header flanges, and the rest of the Summit system. I didn't have to bend anything, just had to trim a few inches from the over-axle pipes and the ones leading into the mufflers. The entire install took less than 2 hours, and everything lined up evenly when I was done. That included tack welding the "extra" joints, as there are 4 sections per side. I'll weld those up after I decide if I like the Summit mufflers, if not they're coming off anyway so I can do the welding then. Initially I wasn't excited about the extra joints, but they allowed my to adjust the pipes so everything was tucked right up against the floor. Definitely impressed, especially for the money.
