What needs to be measured at 3" on the headers for these to fit. I have a set of Hookers on my truck but I think the exhaust hole is 2.25 or 2.5?

Most Hooker Headers are 3" collector. My Hooker collectors are 3" and these bolted directly to it. One of the bolt holes is slotted to help bolt pattern fitment. My outlet pipe is 2 1/2". I wish I hadn't thrown the box away already; it has a chart with part numbers and exact collector and outlet sizes. If you can find that chart, you might get an exact fit. Hooker and Flowtech are both owned by Holley, I'm not sure you can get a "purple Hornie" that doesn't have a 3" inlet.

No, it will not work. Your stock exhaust size is 2". This one is just a little too big. Unless you have changed your whole system, then it would work.

Factory exhaust for a stock common rail Cummins is 4". You may want to measure your muffler length before purchasing this pipe. Mine was longer than this and there was an offset to make it fit right. Some diesel performance shops will have the correct length and offset.

The headers themselves are direct bolt on but you will need new B pipes to attach them to the remaining exhaust. I recommend Cajun-B pipes. He does excellent work.

As long as your exhaust tip is not larger than 3" or smaller than 2" it should fit

most likely it will not. this is for a tailpipe with a 3" diameter. you will most likely need a exhaust tip which will fit a smaller diameter tailpipe. Just measure the diameter of your tailpipe and you will know what size you need.

Not sure, my resonator was welded inline with 2.5" pipe to the 2.5" Vibrant muffler. Just a little louder then stock on my Audi A4

Yeah, I used them in a speaker tube for a 4 wheeler. I used 6" pvc and had to make filler rings to catch the mounting screws. So that hole pattern is closer to 5.5 ". I didn't really measure it.

I'd put a picture up but they wont let me. I have a 2001 cherokee, installed them myself and it is definitely 3 1/2"

Probably not you need to check if the exhaust pipe on your truck is 4 inches in diameter and the overall length of your muffler is 30 inches I believe stock exhaust is 3 inches in diameter and am unsure on length.

Stock is a 4". Reuse factory one if possible and exhaust will fit perfect. If you do not have one, buy from dealer.

Not sure but I have the larger diameter exhaust and it fits snug. I don't even use the set screw. I remove it easily with pliers

I don't think 2.5 inches will work. My bar is a standard 3/4 inch pipe which is 1.05 inch nominal outside diameter. The handles seem designed for about that size. I think a 1 inch standard pipe, outside diameter 1.315 might work, but no larger.

These fit a center hole with a 2.25 inch diameter. The outside diameter is slightly less than 2.75"

1-1/2 inch pipes fit inside the 3 ports. You can get a step up I guess. I wish I could show you a picture of my install. Maybe I could attach to my review.

Only 2.5 inches. My existing holes are 3.5 inches across so my contractor drilled new holes for me.

If using a 1.25 hitch, you will need the Class 2 version (class 1 will NOT work). Class 3 is a 2 inch hitch.
