Since you're discussing exhaust manifolds, does anyone know if there are any headers (preferably long tube) that can fit on the 6.4L AND will not throw any codes causing the check engine light to come on?
-I've asked in other forums with no responses.
I looked into the ARH LT headers and after discussing with a mechanic, he said there's a fair chance I'd have to deal with check engine light problems. The system comes with high flow cats but they are obviously different compared to stock.
I reached out to ARH and this was their response:
"To maximize performance and to eliminate any possibility of a check engine light, proper tuning should be performed. If you don’t want to tune your Ram, we can provide the kit with upgraded GESI cats that will prevent a light. They add $1000.00 to the total cost of the system but most of that cost is offset by not having to tune. The GESI cats are excellent and will do a great job cleaning up emissions while keeping the light off. Let me know what you decide and we’ll do our best to accommodate you. Thank you for inquiring."
I have yet to find anyone in AZ that can perform the "proper tuning" (haven't lived here that long). I'm willing to spend money but $1,000 for upgraded cats on top of $2,000+ headers plus installation just seems wrong.
I'd even consider shorty/middy headers at this point but can't find those either.
Any help would be much appreciated.
