I have a set of Kooks long tubes coming and also putting on their catted Y pipe back to the catback set, for my 2011 Sierra SWB. I have the catback exhaust updated already, but looking to do the front now. Has anyone done the Kooks to their late model? Did it take long to get them on? I have my own two-post lift so, I have the room to do it. Then it is off to update the tune once again.

 

I've never installed kooks, but it should not take too long. Especially with a lift. What Catback do you have right now? I've installed two different brand long tube headers on trucks, and both of them were pretty easy. Taking the spark plugs off, and back on was the most boring part. Let us know how she runs and sounds.
