Steeda Mustang High Flow X-Pipe w/ Cats - 11-13 GT - $499.95

 

hmmmm

 

I would SO love this but after the constant popping of cat-conv codes in my previous car with high flows on it (even tuned for them), I don't think I want that again.

I'm thinking all late-model cars are strict enough in their emissions systems that they'd pop cat-converter inefficiency codes ...

What are the chances that THIS unit would do that?

 

Did they tune for extra flow or turn off the MIL for the converters. Anytime you mess with the location or flow of the converters will usually throw a code. The tuners can turn that off

 

So how much will this change the sound of my car? I am interested in this, but I love my exhaust set up right now.

 

I could turn the rear O2's off with the Diablosport tuner I had for the car ('07 Charger 5.7) but if I left them turned off come inspection time, the sensors would come up as "not ready" for inspection and the car would fail emission testing.

And yes, the car was tuned for it but was still setting codes

 

Rear O2 plugs into middle of cat?

 

I can't comment on the new car yet as I haven't gotten into the tune yet. But in my 98 if you let the sensors on in the tune it would throw a code. But as long as you turned them off you had no issues. I would imagine since same tuners with same abilities that they can do away with the codes. Don't know much about the computers on the Chargers though.

 

I have the rear O2 sensors turned off in my 2011, no codes or issues at all.

 

Not to be ungrateful, but are there any plans for a 11-13 "H-pipe"?

 

I noticed that as well.

 

Bump - what kind of catalytic converters are used in this X Pipe? Are they suitable for supercharged applications?
