Hello, I have a 2019 Dodge Charger RT, Ive recently put on JBA LT Headers , I had a car shop put em in due to inexperience . So, they removed the catalytic converts to get the LTs to fit . So my question (s): I am having difficulty finding high flow catalytic converts suggestions?
Also How would I fing out what items are compatible for my JBA LT headers?
I thank you for you time in answering with usable information.

 

What's the outlet size on your headers? Do they have flanges? Or is it just straight pipe? Magnaflow makes a variety of cats.... just get a couple with the right inlet/outlet size, (inlet to match the headers, outlet sized for whatever pipe you wanna run.)

 

The shop doing the exhaust work can't help?

 

Heyyou, thank you for the information Ill look up the info and go from there.

 

Heyyou, Here would be the headers i purchased (https://www.summitracing.com/parts/jba-6966sjs) the headers do have flanges.
Primary Tube Outside Diameter (in): 1 7/8 in.Flange Thickness (in): 3/8 in.
I thank you again for any information given on this.

 

Collectors are 3". So, you would want cats that will bolt to your 3" collectors. Pay attention to how many bolt holes there are on the flange as well. Make sure the cat matches what header has.

 

Heyyou, Thank you so much for all the help provided so far. As for the exhaust I went back to the shop that helped me with the Headers and they will assist me with the exhaust . the guys there stated that due to the headers not having a clamp on the end we will need to do a weld to get Cats on. Also I have another question when it comes to exhaust can we have a 3" up front from the cats and end with stock pipe 2.75 ?

 

Sure, you can do pretty much whatever you want. If you have room though, I would run the 3" all the way back. Unless you are doing true duals? In which case, 3" pipe may be too large. (for exhaust flow reasons, having room for it is another kettle of fish. )

 

HeyYou, what can you tel me about camshafts? im thinking of putting one in perhaps from Texas Speed. But while looking ive seen stage-1,2, and 3.
What would be the difference of these stages i guess.
As always I appreciate any and all feed back . Thank you for your time.

 

Probably how radical they get. Given how new your car is though, I don't think I would do the cam change.... at least, not until the warranty expires. Also, changing the cam would require a custom tune to go with it as well, which will require an unlocked PCM, etc. Gets expensive quick.
