I looked at the competition version but the only thing is the xpipe isnāt a 3in itās a 2.5 in and the back side is 3in. I donāt think they have a full 3in system
This is what was found when I was getting my long tubes put on never smoked from the exhaust, no oil on the plugs or anything. But this was causing my cat on my driver side to overheat ( thatās why I bought the LTH thinking my cats were failing )
The valve is on cylinder 6. The injector 8 was warranty work. Had a CEL and showed injector 8 was the āproblemā so they swapped it CEL went away then it came back ended up being the wiring harness causing it. And another crazy thing is the car never misfire or drove weird during that issue.
Yes the only one the other cylinders are clean itās crazy itās a 2019 I bought with 5 miles on it in 2019 and the car has 8k miles now I barely drive it because of work and Iāve replace the gas tank wiring harness and injector number 8 itās my problem child š
So Iām having my headers put on and this was found when taking the factory header off no smoke out of exhaust no oil on spark plug and piston looks good. What are your guesses we are still taking the head off and sending it off.
my car on the Whipple tune for my 2019 gt made 650 with stock headers then a couple months down the road my cats started going out and the car made 630. I just got my kooks long tube header with green cats so we will see what we gain with those.
