kooks fit excellent. i don't really like the people at ARH.....I have had their headers and they are of comparable quality to kooks (both are top of the line) but won't give ARH anymore business. plus i think kooks are a few hundred bucks cheaper so there is that, too.

 

you aren't giving up anything going with kooks. i don't consider them a budget brand like pacesetter or stuff like that.

Here is a vid of the startup with stock catback

 

 

 

 

here is an pull from in the cab with stock catback. disregard the Engine Power Reduced notification that pops up, lol.

 

 

I am surprised at how quiet it is. Im anxious to see how it sounds with the magnaflow exhaust. I think i will be going with that exact setup on my 5.3. Are you getting the power reduction message because you havent tuned for the headers yet?

The camera phone doesnt sound any different but it sounds deeper but still quiet. I am pleased.

 

I don't know why that message popped up but never before or after. I adjusted a couple things to see if it's just flowing more air than it expects now.

 

The tip is ridiculous so I chopped it off.

I had a set of Pacesetter LT's on my 4th gen while cheap and they made good power (26+ rwhp sae) the y-pipe fit was poor and a bad design. My 4th gen was also a garage queen (28K mile '94 B4C AutoX/open track car) and they had already rusted after two years. I'm actually more familiar with Kooks than ARH as I remember them from my f-body days.

 

Ryan, I checked with Stainless Works and they don't have anything for 2014's yet.

 

I'm going to buy a set of longtubes with cats this fall and get the truck retuned. I may go 1-7/8" in case I upgrade to a supercharger in the future. Attached are some pics I found of Kooks on a 5.3.

No pics or vids or anything yet but with the stock catback I am really surprised and happy about how QUIET it is. It sounds like stock, honestly. Usually long tubes wake the neighbors. I installed the Kooks Y-pipe with high flow cats.

 

So now I am debating a catback, its not a no brainer for me to get one. I do not want a loud exhaust at all on my truck, I was worried I would have to install something quieter than stock.

 

Stock catback must be REALLY restrictive or really well designed....usually catbacks are good for 5 HP. If it is this quiet with long tubes.....could it be worth more????

Higgs... Same boat. Just picked up kooks/off-road Y. I'm gonna mate to stock exhaust because I really like the way yours sounded but I'm curious if your magnaflow is causing migraines and if you noticed any change in tune after new catback that would show any measurable increase in airflow?

The Magnaflow sounds so good. It doesn't represent on the video, it is super quiet at low throttle positions but sounds healthy, almost big blockish when you roll in a little bit.

 

I can't say enough how happy I am with this set up. Kooks LT, catted Y, Magnaflow catback. It's not too loud in any way.

 

My fuel trims actually did not require changes to MAF or VE, except at WOT, I did adjust the MAF a bit.

I'm wondering about access to spark plugs, proximity (heat) to other components, wiring, etc . Can you share your opinions and pix of your experience?

Better access to spark plugs

The only thing close to the headers is the plug wires but they don't touch.

On my car I run stock plug wires with heat sleeves and on the truck I have taylor wires without heat sleeves.

The Taylor wires can be arranged so that they have lots of clearance. I don't think you will have problems with either.

I could put sleeves on the truck but it doesn't seem necessary so I haven't bothered.

Good question, did you coat, shield or wrap anything or wish u had? Any noticeable underwood temp changes? Jet-Hot is about an hour away but I keep hearing that it's not necessary on Kooks, even from Nick at Kooks.

Nope, I would do it like this again.

Love the wires, I have been searching for a set and those look like they will work better on the passenger side front two cylinders. Got info handy?

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.

      Yes your absolutely right, I been looking at the 4 inch BDS one and it acutely states you can use the stock 20’s just not the 17’s or 18’s, I also didn’t realize that with my 275/60r20 stock wheels I’m already running 33 inch diameter wheel setup lol so I can just run my stock wheels and tires atleast to start.

      I would expect that to be lift-kit dependent.  If the kit has interference issues w stock wheels, then the kit/manufacturer should indicate that somewhere.
