Bullet Performance Exhaust + Dyno Tune

Hey Everyone,

 

I wanted to share my experience with these mods I've done on my RCSB

 

1-Bullet Catback Exhaust ( including valved cutout )

2-Kooks Long Tube Headers + Catless (Offroad) Y Pipe

3-Volant CAI

4-Dyno Tune

 

This combination of Bullet + Kooks gives the truck a really mean sound and it rumbles like a Vette

not exaggerating, but it really does in person IMHO

 

the special feature about this cat back is that it has valved cutout, so when ever you feel like you want your truck to sound like stock exhaust, its just a push of button away as you will be seeing in the video bellow

the exhaust sounds really good, very minimum drone when installed with Kooks catless pipes, no drone what so ever with stock headers & cats

 

first of all lets hear how does this catback sound with Volant CAI and stock headers and y pipe ( valve testing in the video ) earphones recommended !

 

 

 

 

 

and now lets hear how it sounds with kooks long tube headers and catless y-pipe + tuned ( valve testing in the video ) earphones recommended !

 

 

 

 

 

So what are you thoughts about the exhaust?

 

and now with the Dyno tuning

 

Enjoy !

Wow that's pretty cool. Can you post more details and photos about your setup? Tell me about the cutout and how you operate it from inside the cab.

Very soothing!

 

These exhausts which allow for stock volume are beginning to appeal to me. It's just so practical for a daily driver. No more early AM cold starts waking up neighbors or rattling pictutes on the walls!

 

Great videos as well, love how you drove it in manual. Cant wait to get exhaust on mine!!

Awesome job man. I really want to test one out. Lol

Thanks mate!

you can see my setup in Vehicle Build section, here's a link

I do have a Remote which has on and off buttons just like this one bellow

    • Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/        
    • UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update  
    • GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.  
    • Thank You.   So far my new ride is making me look like a genius for going with the 3.0L, as my first fuel refill occurred over three weeks from when I took delivery.  This engine combination is very amazing.  So far no issues and had not done a regen yet.
    • I am curious as to how much fluid you put back in the transmission ( assuming you had replaced the filter to compare to my findings ) and then went through the process of warming up the trans before pulling the check plug to drain out the excess and if you measured how much came back out.    I just found it surprising that some claimed a certain amount less fluid being put in and then draining some back out. The attitude of the truck as per if the surface is level and how the trucks stance is would make quite a difference since the check plug is right at the front of the transmission.
