Anyone installed a set yet? Haven't received the 2021 I ordered in September but expect it by New Years. Gonna call it a 2022.
I had a set of these on my 2007 Roush Mustang. It was cool to open them up once in a while but this particular brand had a tendency to leak at times giving the computer false O2 readings, therefore I got some dash alerts and back to the tuner. Anyone have a set of good ones that would be recommended? Or maybe not install at all?

Plenty loud without it you'll see and it would cost a little hp when open

I have never had or known anyone else who had a set that did not start leaking after some time.

QTP’s. 15 years reliable on the 440. EFI so it does have sensors.

 

[Booky]

I had the NOWEEDS on my 2016 Challenger Hellcat. No issues at all.

I had QTP’s on my 540 Camaro and they worked flawlessly. They were fun, but didn’t make a damn bit of difference on the track. That being said, I personally would never put them on my SS. I think it would be immature to put them on a $100+ car. Besides, the stock exhaust sounds awesome as it is.

Thanks for the input. Although I take issue with the immature comment!! Might be true anyway. I don't really care. have been accused of being childish at times.
I will wait till I get the car; just anxious since it was ordered back in September. Trying to anticipate what accessories I would add to make it my own. Most of us do that to some extent.
I come from old school hot rodding so I have some old ideas as uncapping the headers gains power, not reduced power as was stated. I learned something here.

I never said I wasn’t immature! Hell, sometimes I even take pride in it!!

Agree!! I was taking it with a smile and acknowledging it as a badge of honor at times.

Does Dodge install headers on the Redeyes?

had them on my c6 vette for 20k and they didnt leak. that said i didnt use them all that much because the drone inside the car about drove you nuts and it wasnt loud it was LOUD! With my 6.4 i went with a zommers exhaust. It is plenty loud enough. little to no drone and nothing mechanical to break. It sounds like a muscle car should. But i dont know if they make it for a hellcat. But if they did thats what id have on mine. Hands down better sounding then a corsa or a borla and as good as sound or better then a flowmaster without the drone. plus it looks as pretty as jewelry!

They make the perfect Christmas gift for boomers and mullets.

The big block 440 is raucous uncapped. Most fun setting off car alarms in parking decks in Reno. QTP’s always sealed and survived some compressions on route 66. Durable. Put the switch in easy reach. Also, the duration to full open is 3-4 seconds. A little, lot, or lot more.

 

[jakelind707]

I put QTP cutouts on my cat after the mid-muffler because I didn't want just header dumps but wanted more rumble. was the best decision I made. they were great, electronic switch in the cab, whenever a cop got curious I'd close them and stay in 6th.

Are you fourteen years old? Fun for whom?

Nah. 16. Just between the ears though.

Thanks for that info. I did not know about Zommers. They do offer them at $1500 for the Hellcat.
I am going to wait till I get the car and drive it a bit before I go spending a bunch more on it.

if you like that raw muscle car sound from the 70s you wont be disappointed. there not cheap though but then it isnt like a set of flowmasters thats going to be shot in a couple years.

If you want cutouts deep down it's a craving for side pipes and a big ole cam for the rumble......I understand fully.

I do but not to the point that you cannot enjoy conversation in the car.
Who is the manufacturer of your Cobra? I always wanted one. I have a friend who has one. On a 1 hour trip with him, I enjoyed the sound but he wore ear plugs and I sat there cold. Nice car and fun but after that experience I would not own one.
