Catless DP makes less pops

[zrk]

correct, but some may be unaware that when they press their sport button the valve will not actuate to open as the JB4 is controlling it. I needed to “unclick” the setting in the JB4 so the sport button operated as normal OEM.

Yes corrrect

Also Armytrix catless dp with no cel! That o2 simulator is nice, I posted pics comparing it with my old Titan catless dp in my build thread as well

I was thinking of getting armytrix but $600 for a catless DP is crazy just picked up an AMS catless BNIB I’ll just deal with the CEL

I picked mine up used off fb marketplace for $300, only reason I was able to tell myself to go Armytrix. $600 definitely up there in price but there is that peace of mind that there’s no issues too in case a CEL ever does come up

That makes sense if i can find one used for a reasonable price I’d jump on it! I might try the big daddies garage 02 spacer/defouler I’ve heard mixed things about them working though

This def seems the way to go, as I can bet the perm code i am getting is causing the ecu to stop the pops for whatever reason.

Fun fact, I read this and thought to myself... I should check my BootMod3 settings (I had a suspicion my valves weren't working correctly)

I was right, my exhaust is now loud af again with plenty of pops. Lol. The dumb ass "open" setting for exhaust sport mode was fighting itself apparently. Selecting OEM made it work as expected when switching from Normal to Sport mode, etc

Aaaahhhhh that's what you're talking about. Ok, that makes sense. Was aware that was happening. I personally haven't had an exhaust valve since there was about 1500mi on the car so nothing to control.

Where is this setting in the JB4?

Again, not to create another thread, and kind of hijacking this one: What's considered the highest quality catless downpipe out there? I know it's just a pipe with some welds, but there's also fitment to consider, quality of steel, etc. I'm not concerned about cost and would rather pay more for a quality product. I'm also not concerned about popping a CEL, because this is something I will be putting on the shelf until I'm able to have my current untunable '21 tuned.

All catless downpipes will sound 100% the same, second, this his happened to a few clients and it generally comes back in a few days, as ecu re learns and re sets itself, also fuel is a factor, put a fresh tank and see what happens.

The highest quality pipe is the evolution racewerks. It's handbuilt in the US. Best finish, wielding, etc..

Many brands are proven to fit without issues, Evolution Racewerks, Active Autowerke, MAD, etc...

If you get a proven brand, it'll be 304 stainless steel. The cheaper eBay ones use the 201 lower quality steel.

I second this i have AMS catted to AWE resonated touring with JB4 and it pops and cracks like crazy… hell I’m considering switching to catless just for more pops

PLENTY of pops bang and gunshots. Wouldn't want more, I'm also on jb4, I'm not sure if ethanol makes any difference but it tends to pop more running e40 than with 93. Not sure if it's just anecdotal.

Hold BC button for a few seconds and your blinkers will flash, right open, left closed, both on= normal setting controlled by sport button.
You can do some silly loud cold starts this way if u hate your neighbors. Jk, luckily all my neighbors have loud cars

See, I tried this.

The right blinker keeps them open no matter what. The left blinker and both blinkers keep the valve closed no matter if I'm in sport mode or not.

It will work (i think), after you switch it to both blinking, restart the car and try to press sport. Report back? This is what I had to do, it was tricking ne good for a hot second but ultimately the solution was just to turn car off and on
