Mac high flow cat h pipe or Off Road Prochamber H-Pipe

[emlaxstar9]

ok well i am decding which one to go with but i dont know which one to pick. any suggestions?

and im going with a mac cat back system

 

[booby]

are u keeping the original h pipe come inspection? need to have those cats in there, or its a :nono:

 

[emlaxstar9]

damn so should i just stick with the flow cats.. would that pass inspection?

 

[booby]

large diameter high flow cats don't get hot enough and come close to failing the dyno test alot of the time. but it will pass the visual inspection where the guy just takes a glance to c if u got cats.

maybe some1 else with more knowledge can chime in? i was tryin to figure all this out myself when i purchased my exhaust setup

 

[emlaxstar9]

i know now im trying to figure it out.. what if i had mil eliminators on though?

 

[booby]

not a 100% but im pretty sure mil eliminators only trick the car's computer into thinking everything is ok, so not as to put a CEL light on. but its not going to change whats actually being emitted by ur vehicle. for inspection, they are testing emissions

 

[emlaxstar9]

so that wont help when they look right? so i should go with high flow?

 

[booby]

ur taking a risk with high flows imo. try finding some1 who has em and see whats up. in the meantime, check out this place to make ur exhaust decision:

+1..if ur worried about going high flow's and having the same problem as having no cats u should just go with the prochamber n swap it out. atleast this way uk wut the outcome will be.

i have prochamber, high flow and mac mufflers, no inspection issues

 

[neckbonekat]

I have high flows cats and never failed inspection. I've never known anyone with high flows cats that failed inspection. At least not unless they altered them in some way.

I agree, go o/r and swap for inspection, unless you know somebody that will pass you. In the meantime you can make your own Mil Eliminators to keep that CES light off. Here are instructions: http://newyorkmustangs.com/forums/how-to-make-mil-eliminators-your-mustang-t4015.html
