Hello everybody, I’m trying to narrow down some things on my car, and I’d appreciate any input. Sometime over a week ago, i started hearing this obnoxious rattle from under my car while it was running. And a few days later the cel kicked on. By then I realized it had to be the driver side cat. I...

What is everybody’s experiences with after market catted mid pipes. X or H. My car needs the cats replaced and I see these high flow after market mid pipes. But I’m just curious if they do actually pass emissions and keep the check engine light off. Any suggestions ? Especially affordable

My 2007 Mustang V6 (over 140,0000 miles) started to make a noise, which sounded like metal hitting metal. At first it was barely audible, but then last week it got even worse. I would hit the gas and the metal hitting metal sound was loud and clear inside the car. When I popped the hood it...

Have any of yall in north or south Carolina who have done catalytic converter delete had any trouble with the law or passing inspections? Thinking about doing it to save some money.

2006 Mustang V6 Convertible has a loud rattling noise coming from underneath the car about where the shifter is. I don't know if it matters, but it is much louder and consistent when the air is on. I've heard it could be the heat shield for the exhaust or possibly the catalytic converter. Has...

I'm currently dealing with an issue with a mustang I just bought that has been sitting for a year. After replacing the fuel pump and a new battery, I was able to get her running. Problem is I have a serious lack of power and around 3k RPM the exhaust hose that hooks up to the EGR position sensor...

Hey guys I have a 2007 Mustang GT, I have installed long tube headers and an off road x-pipe about 6 months ago. I have been getting error codes P0133,p2195,p2196,p2197 ever since. I did install a tune using and SCT tuner from brenspeed, and I have replaced the 02 sensors but still keep getting...

Hi - I'm hoping the forum members can help me confirm / diagnose what type of exhaust system is presently on my 2006 Mustang GT and make some recommendations on replacement parts. I don't know the history of the car so I've been reading through the forums and trying to make some educated...

My 2011 5.0 has only 36,000 miles on it but I've already replaced both catalytic converters in the last year and my check engine light is on (again) and it is throwing a P0430 code. What would cause this? Could it be related to my supercharger? I can't afford to keep replacing the cats...

Right, I have the rear section of my exhaust already done, its a custom built S/S system from the connection pipes after the cats. It doesn't have back boxes but 'boosters' which are basically empty high flow mufflers that just keep the cops happy if they look underneath. (here in England you...

So my 2003 V6 started making a loud noise and upon investigating I could see that the factory welding on the exhaust before the catalytic converter has come off. I have seen many threads which say that the A/C drips off on the manifold on the passenger side and it's a common problem for the...

I am really wanting to do long tube headers on my 2005 Mustang GT, but I didnt realize this means no cats on my car( as far as i know, please correct if im wrong). This is an issue seeing as it is my daily driver and im going to need to pass Texas state inspection in March. I have a C&L intake...

What's the worst possible punishment for getting caught with an off road x pipe on the street? Any fines? If so how much? Does anyone have any experience with that? Please share if so... How could I even get caught with one in the first place? Thank you all for your responses I greatly...

I'm debating hollowing out my cats on my stock h-pipe, I'm not expecting any significant performance gains, but I would like the added sound for my stock 07 GT. Where I live there is absolutely no emissions testing, so that's not an issue. Do you guys think this is something worth doing in my...

Hey everyone, so I've accomplished one of my life dreams, which is owning a mustang :) Last week, I bought a used 1986 5.0 mustang convertible and the original owner told me during the test drive that the catalytic converter rattles sometimes but then goes away. I was informed that this means...

I have stainless steel headers and h-pipe with no catalytic converters. It's inspection time and I want to pass with no problems. I want to put the catalytic converters after the h-pipe because I will be getting rid of it for a turbo system. I also think it will be much easier to install in the...

I failed emissions testing on my 2002 gt and I was told I need a catalytic converter and an o2 senser. The emissions guy said the converter will cost me around 800 dollars but Im finding them for 200 on websites. Is there a type of converter I need to buy? The service engine light passed and...

Hey guys having another issue with my 2001 mustang v6 3.8L a while back i had the catalytic converters on the driver side replaced cause i was told the were bad and cased the check engine light to come on. well when they were replaced 2 completely different ones from the orignal ones were used...

Cats are supposed to last a good while. I have 141K on my car. I know that if it's time to change them, a check-engine light will go off. Recently during idle I'm smelling a fuel odor coming from outside, can this be a pre-mature sign for new cats? Thanks guys!
