I'm almost Canadian... Minnesota. The underwhelming Wild have me extremely frustrated right now though.
Also, there is a way to reuse your stock fuel rails with the return setup. You just have to either remove the crossover tube and make a custom one (like with AN fittings), or I think some people have managed to massage the stock one enough to get it to work over the bigger plenum of the TBSS style intake. And you have to drill some different holes in the plastic tabs for mounting the fuel rails, but that is very simple.

Sorry, didn't see this. But like GI.SS said, it is the correct fuel rail set up for a returnless system. Same GM quick disconnect fuel line connects to this as the one that does to the factory fuel rail on my 2004 SS. I think some year SSes have a return style fuel system, so those would require a different rail setup or to modify your stock rails to fit over the larger plenum of this intake.

I am de-modding the truck in preparation to sell/trade, so this intake setup is for sale. Comes with everything needed to install it into a SSS or on any LS cathedral port engine. Included is the intake (with MAP sensor and EVAP solenoid), 39 lb/hr TBSS injectors, return less fuel rails, 87mm truck TB, gaskets, Xlink 2.1, and injector adapter harnesses.
I hate to see it go. This thing made a huge difference in throttle response and drive ability and more top end pull. I did some minor "tuning" on it and used some timing and fueling table values from a TBSS as well. These engines should have had this intake setup from the factory. I never dyno'd the truck, but the difference was noticeable.
$600 shipped to CONUS/BO

You can radius the oil pump outlet as well to get better oil flow while you are in there. It's a simple task with a Dremel or similar grinding tool and good insurance. You can shim the pump relief spring to get slightly better oil pressure too with one washer. I have also used LS7 and Comp lifters with good results. I spun a 5.7 LS over 6500 regularly road racing a Trans Am with LS7 lifters and a slightly more aggressive cam than the one posted above and it ran fine for years.

Never heard of this coating deal. I have heard of the needle bearings falling out of rocker arms on earlier LS engines, but I think that was mostly on early Fbody and Vette 5.7s. Higher mileage LS engines often have very audible piston slap that is more pronounced when cold. A good inspection of the upper valve train is a great place to start to rule things out.

For those thinking about this mod, do it. It should have come this way from the factory.
I did this mod but reused the stock injectors (plan on putting in the larger TBSS ones eventually). Used an 87mm truck TB and Xlink. Mine was returnless so the install was pretty easy. Modified the EVAP line with rubber fuel line and that is about it. I modified the timing tables to match what a newer 5.3L truck engine with the larger intake and TB like the TBSS one has as well. Peak WOT timing is actually higher on the SS tune in most areas, but midrange timing is more aggressive on the newer trucks with the bigger intake and TB. The SOTP difference is noticeable as far as peak power, but the bigger improvement is the part throttle power and throttle response. It feels like it takes half the throttle it did before to accelerate normally with traffic and it is much more crisp feeling.

PM sent.

Stock 87mm truck TB with Xlink.
-
Thanks for the intake, it is installed and generating smiles.
I just put it in with my stock injectors for now until I either buy HPTuners or have it tuned. But even with the stock tune I can feel better throttle response and power (I know, I know, the butt-dyno often lies....lol.)

I'm not sure where I am in line, but PM with offer to buy for listed price + shipping sent as of 5:38pm yesterday. Just want to be transparent with everyone.

My overall is usually 14.5-14.7. I don't beat it hard, but I enjoy the truck from time to time
. Cruising at 75 it reads about 17 on the cluster, but at 65 it will get 20+. That is with the only mods being a CAI and Magnaflow muffler (now swapped for a Flo-Pro). So if a guy wasn't always having to be the fastest guy on the road, 15 overall should be easy on a bone stock truck.Towing my car trailer with car on it, it gets 11-11.5.

I still want a black XL hoodie....
EDIT: In fact, you still have the Paypal funds I sent back on 10/26

I agree. It flows less, but probably enough to support my current setup (stock everything except a K&N FIPK and MSD wires with TR55 plugs). It feels pretty much the same, but we all know "The Butt Dyno" is not a precision instrument...lol.
The next mod I do will be the 07+ (aka TBSS) intake and 87/90mm TB, but that will be spring time (tax return). Then probably headers whenever I have the free cash next year.

So..... The day has finally come. I had the Flo-Pro muffler welded in place of the Magnaflow this morning and all I can say is I wish I would have done this a long LONG time ago! I can't say for sure, but it is probably only slightly louder than stock. I can't remember what mine sounded like with the stock muffler aside from being very quiet. It is significantly quieter than the Magnaflow in all conditions. It is very quiet at idle and part throttle, but does have a nice throaty sound at WOT. I would say it is in the neighborhood of 80-85% quieter than the Magnaflow. BUT! There is ZERO drone at any speed.
The question at this point is will it affect mileage and power negatively, since it really cannot possibly flow as good as the Magnaflow. I pretty consistently get 14.5-14.7 MPG on normal weeks driving to work and a few errands, so I will be able to answer that in a few weeks. Power, I will really never know. I did run the truck on the 1/4 mile with the Magnaflow setup a couple of years ago, and ran 15.1 @ 90. But it was an impulse decision to even run the truck and I got bored watching my wife run her WS6 that I had towed to the track and decided to drop the trailer and run it
. That will probably never happen again... It should flow better than stock though since it is actually a true 3" dual in/dual out muffler vs. the stock one with it's dual in/single out with resonator.I am 100% happy with this change. It is exactly what I wanted. If I really feel I lost power and efficiency and want more flow from the exhaust at this point, I will look into long tube headers and high flow cats and keep my quiet muffler even if it does cost me a few ponies.

I have a Prodigy 2 and it works very well and is plug and play with the tekonsha harness. Can get a little touchy creeping through parking lots in B2 setting and the base voltage set too high, but other than that it works flawlessly when I tow my car on my open deck tandem axle car trailer. If I get the settings just right, it will feel like there is no trailer on it under braking. When it gets a little touchy it will actuate the trailer brakes a little much under very light braking and pull the truck down instead of being even and smooth. But I am picky about getting it set right - it is not hurting anything and lots of people probably wouldn't care.
-
Got the FloPro the other day... looks like a nice unit. The outlets on it are custom offset to line up with the factory "Y-pipe" tailpipe instead of being just evenly placed on the face of the muffler. I will be putting it on the truck on Monday.... more to come after that.

Picked up the Nitto tires from Tim two nights ago. They look great, as advertised! Thanks again Tim, nice meeting you, and your truck is awesome!

Even stock exhaust on an SSS sounds decent to me compared to average vehicles going down the road (like a Prius for example), but I agree, it is a pretty subjective topic. If I want to raise hell or impress people with how loud a vehicle is, I'll drive my Trans Am that runs low 11s and has LTs, no cats, and a single 4" system on it
. I want my truck to sound "good", and most of the time I like my current Magnaflow setup and feel it does sound good and not too obnoxious but more tone than stock by a long shot. But no amount of good sound and additional flow is worth this drone on the highway. Maybe my current setup with headers and no cats would sound good and not drone... I just don't want to do extensive mods on the truck right now, so I will see if this FloPro is the way to go at least for now. If it doesn't, I will definitely look into adding resonator tubes that run opposite of the flow direction. -
Lol... in my defense, I was the first one to send money thinking a shirt was there and the post did still show one being available....lol
At least you know there is some interest, right!?
-
What version X-Link? Did you buy it new?
-
I hear ya Jake99 (no pun intended)! It is literally painful at around 70mph. If I was more brave, I would try the resonator tube along the muffler body and see how that works as well. Definitely keep us posted on your results!
I have one 12599 (3" DI/DO with integrated X, 22" long, oval body) and two 14419 (3" SI/SO 14" long, 4" overall width, round body) mounted in the pipes right before the muffler. The droning is only very slightly lower with the added mufflers in front of the 12599. I initially installed the 12599 by itself to replace the stock one.
The thing about tubular piping and flow is one has to consider the effect of laminar flow and how it effectively reduces the volume of air that the pipe can move. This is why dual 2.5 pipes will never flow as much as a single 5" pipe. The lesser surface area of the large single tube means it will outflow the two smaller tubes.
And there is almost nothing we can learn from a race application exhaust system when it comes to daily driven street vehicles. Race applications mean WOT nearly 100% of the time and zero care for loudness or drone. Scavenging is the only positive thing an exhaust system can offer to help make more power (or shape power) compared to no exhaust at all. Backpressure is never a good thing. I think when some of you say backpressure, you mean a scavenging effect. That may be due to pipe sizing and bending being tuned to create velocity in the system or by merging multiple banks (or primaries in the case of headers) together at specific distances and angles.

I had it posted locally and another guy had committed to buy before SSSNCHA contacted me and posted. The sale went down this weekend so that is why I waited to post anything else. So it is sold, sorry guys.
