Best headers for 03' Yukon?

[blueflamed03]

Shouldn't take much more than 4 hours. Shorty headers are a waste of money

Ok, I was gonna try to use the stock exhaust. What are a good type of high flow cats since I've made my mind up that I am gonna get long tubes. Will I have a problem with o2 sensors, or are there bungs in the headers for the sensors?

Thanks

Is this the style you have with the cats Max?

Thanks

do you 'need' cats, do you have visual and smell inspections?

I had a y-pipe and full 3" built for mine since the 6.0 trucks are different from the 4.8/5.3. Those are the same headers tho.

Awsome! If I get long tubes, my current exhaust will have to be chopped up so the factory cats will work. So thats why I thought that it would be easier to get the header/cat kit. It also connects into the factory exhaust so I will still be able to have the current exhaust as I have now!

Be sure to get a tune or you won't take advantage of the new found power, I also gained some solid mpg from them as it drops duty cycle on the injectors by about 10%.

Yep! I already have it lined up for a Black Bear Scan Cable Tune!

Thanks
