i believe there are 4 catalytic converters on the 2013 mustang gt. my question is if i remove the last two and replace them with the outlaw mufflers by flowmaster, is this going to mess up the tune or when it gets inspected. if anyone has any info that would be great. i want to do this because...

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!

hello everyone, i have some questions about catalytic convertors, is it legal to replace the oem ones with performance ones in CA? does the engine light turn on when they are replaced, but not deleted? thanks guys,

How can i get the loudest, deepest sound my 2012 v6. Whether it be doing something to the Cats, such as just using a test pipe, or a whole new exhaust system.

I bought a 96 SVT Cobra about a month ago. It had 39K miles and was a garage baby. The previous owner only drove it about 1.5K miles a year and seemed to spend more time polishing it than driving it. I trusted the seller totally. But he either forget to mention an issue or it went bad 5...

I don't know if this is possible or not but is there anyway to turn your catalytic converters on and off with a switch or something? Right know i have dual ford racing exhausts that are alright but I what a more aggressive sound. So if worst comes to worst i can always buy new exhausts or just...

so im going to install obx long tubes on my 4.0 and the cats are coming out. so i was thinking about installing a high flow cat after the Y connection for several reasons: volume, and so when i go to sell the car i cant tell them the truth that it has a cat, and also so i feel better about...

I have a 2005 v6 and will be installing MAC longtube headers at some point. This will require me to get new catalytic converters. The stock cats have O2 sensors going right into them. so i am left with options and my goal is to not run lean or throw codes. Are new cats that have the O2 bungs...

New Member. I was told by the Ford garage I need a catalytic converter replacement for $4000. Any suggestions for a cheaper path?

I am completely new to the Ford line and even newer to the 4.6L mod. motors and mustangs in general. I posted my introduction and received a lot of advice on updating my non-PI engine (will start this once suspension is replaced). Purpose of this thread is to find out from seasoned Mustang...

I just acquired a 2004 GT with a whole list of mods. Notably: cold air intake, throttle body, plenum, headers, short shift kit, and Flowmaster exhaust. The exhaust had no catalytic converters and now the dealer is installing them for free but aren't installing high-flow CATS. I'm wondering...

My 88 Notch is having a little trouble passing smog, the HC reads (146)reads just a bit over the MAX limit(121), and the CO reads (.78), the MAX is (.76). I live in CA, so they are very strict about it passing smog. I changed the Oxygen sensors, and the guy says that I may need new cats. Can...

Hi there, So I've detailed my 5.0's engine a few times in the past using information gathered across the web. In a nut shell, I run the engine to warm it up, cover my alternator, distributor cap, and one or two other components then spray it down to get steam going. Then i wash it with a...

Hi! I just got a 1994 Mustang (3.8 V6 Auto Transmission) last week. Lovin' it :bigthumbsup... except for this problem.... For you guys who want me to get to the point right away, here's the question: **Assuming I have a damaged "cat", Can I "punch" or somehow remove the catalytic...

I have a 1989 Mustang 5.0 LX with a little over 100,000 miles. Recently it has begun shutting down after running consistently for 150-200 miles. It acts like a fuel line problem. It begins to hiccup, lose power, and eventually the engine just shuts down. I usually hear some pops in the exhaust...

hey i got a V6 2003 mustang with a true dual exhaust, a cold air intake and after market mufflers(although not flowmaster or anything good). Im trying to make a little more sound out of my car to give it a more agressive feel but im not sure of any other way to go about doing it. at full...
