You can buy headers that split for a 3 and 3 setup instead of all 6 going into one down pipe. I think the cheapest I've seen for one is somewhere around $300. Not too sure how you'd run the piping, and hook up the extra 02 sensors, but if you can make it work, go for it. I don't care for the look of duals on a XJ, but that's me.

 

No offense, but I think the location of our gas tanks makes this a tad dangerous man, lol, I don't like the idea of flames shooting out of my exhaust anywhere near MY gas tank,lol.
I did have an old '62 Chevy shortbed fleetside that was lowered and wanted to put one of those kits on it though, on certain vehicles they're really cool.

 

How would one prevent the unburned gas from eventually plugging up the cat? Or even just totally overheating it since they generally run at 900+ degrees the extra gas is going to burn there first.

If you remove the cats, I can see it working well.

 

Here's what it looks like when the pros do it.


Of course, these guys are using high pressure gasoline injected into the exhaust.

 

And here's what it looks like when done old school with a carbureted V8. You can hear them rev up, cut the ignition and them you see the flames.

 

Sorry its taking so long to do an actual "for sale" thread. I've been busy working on the XJ.

Anyway, tonight I'll be getting a vid of my buddie's 1998 Camaro with my kit on it. I'll also have pics of a kit I built for a different buddie with a 2002 Camaro.

I've also got a vid of a 50s Caddy tossin' flames, but I've been hesitant to post the vid as its not a car using the kit I made.

 

This way.. Pacesetter headers
