Longish review if interested:
I got them over a month ago for about about a $100 shipped for a pair of cats. They each have an O2 port for EFI, but they come with plugs if you don't need them. You can't see them in the pic because they're on top. I bought the 2.5" in/out.
Easy install, only needs about 8-9" or less cut out of your current exhaust and at least 4" diameter of clearance. I used a chain tube-cutter and total install was less than an hour for both sides. I didn't even have to remove my exhaust system.
I used Megaclamps for a leak free install, same style I've seen used in big rig diesels, but you can always weld them if you want. I like how i can just unbolt the entire system when needed.
Pros: I can't smell anything when idling or at cruise anymore but I still smell something at WOT but it's a processed cleaner smell vs. raw fuel. My exhaust exits the sides but I still got fumes in the past, now it smells more like a modern car. I wonder what it would smell like with 4 cats total!
No discernible extra heat from the floorboard.
Drawbacks: Reduced the sound of my Flowmaster 44s quite a bit. But I thought they were a bit too loud anyways. But I kinda miss the raspy burble when downshifting. And horsepower feels a little bit less but hard to tell how much with just a butt dyno. Torque may still be the same or slightly more but again hard to tell.
I don't know how long they'll last with a carb set up, but I can simply unbolt them or get a new pair when needed or reinstall a straight pipe if i want LOUD again. Probably would take less than 15 minutes now that the pipes are already cut.
