I'm about to do this on my 21 Acura TLX TYPE-S & was wondering if my valvetronic exhaust is closed will the start up still be loud? I'm also running an aftermarket cat back valvetronic exhaust & currently waiting on a 3inch high flow pipe which is back ordered in place of secondary cat.
Quit saying secondary cats... cuz they aren't catalitic converters.. those are a honeycomb ceramic.. what your talking about are a steel mesh resonator.. they are just to keep drone out of the cabin.. nothing to do with catalyst.. thats why they are behind the 02 sensor!!
From what I could find, the factory exhaust (at least when it is equipped with the dual mode exhuast) doesn't have a distinct resonator. Though the very large NPP muffler seems to be a type of resonator+muffler design.
@@sim.plevlogs Ok thanks! I put money down on one yesterday seeing if they approve me for a loan while I have a loan on my mustang as well. If all goes through I should get one sometime this week!
“Stealth valves closed” *still loud af* 🤣🙌🏼
Honestly it’s a good mix, good enough for a cop to think the car is stock lol 😂
Apparently those are actually resonators. The inside of those are metal rather than ceramic. So they're just sound deadeners.
🔥🔥🔥
🙏🏼🙏🏼🙏🏼
Did you get a check engine light or anything like that cuz of the secondary cat delete?
No lights at all
@@sim.plevlogs same no lights .

Tbh not sure on your car… but on my mine honestly wasn’t that loud with the valves closed sounded stock
@@sim.plevlogs That's exactly what I want, it doesn't have to be loud on startup just when I wanna mash on the peddle. Thx for content
@@djsthemetereman anytime! 🤞🏽🙌🏽
What size pipe did they use to replace the secondary cats??
It was the regular size of the exhaust and they just opened the ends of the pipes… i don’t remember exactly what size it’s been over a year 😳
Can you post with the aftermarket x pipes after installing?
I actually already have! Check out my recent Vidoes
They're not catts, but resonators.
Whatsup bro where in Cali did you find a shop to do this? I live here in the 209 area and shops don’t wanna delete my second cats! Thanks

@@sim.plevlogs I don't have Instagram, how about on Facebook?
Doesn’t that mess up your warranty?
Honestly not sure lol
Are the secondary cats basically the resonators?
No, just smaller cats

@@markb1511 got it thanks
I did this and my check engine light came on any ideas on how to fix it?
I’m assuming it’s from the mid valves you can buy a plug to conduct the sensor or have a tuner tune out the code
@@sim.plevlogs thank you!
I don’t know if those are cats, maybe resonators?
These cars come with 4 cats… they have a resonator farther back
@@sim.plevlogs Where is the resonator at? Is it in the factory X pipe?
@@evanhuskey6997 yes around the x pipe

How do you pass emissions?
Yes I do!
Secondary cat delete will not effect smog
The things he deleted are not cats, they are resonators. I don't know why everyone calls them the "secondary cats". They are part of the AFM system.
@@hecticphusion this is for emissions, the afm valves are located else where in the exhaust
@@richardsturgis7540 no, these are the AFM valves. You will get an AFM fault if you disconnect them.
