I have an 02 F350 7.3 extended cab long bed- with all the research I have done, many people rave about the 4" MBRP turbo back straight exhaust- without a muffler....Here in Tucson the few shops that can GET the product, know very little about the product...the shops say that they can only do a "Catback" system because there needs to be a Cat Converter....if so, then how are so many people getting away with it going with the straight pipe system?? I am sure I am not the only one that has to go through emissions once a year....do you FAIL emissions without a cat converter?? I was hoping to be able to go to a reputable exhaust business that know about this kind of stuff and make me feel comfortable with their knowledge and be able to answer my questions and offer a warranty....I have gotten a big fat ZERO so far....I want to add a tuner to my truck and know that it is essential to lower the EGT's with a 4" straight exhaust- I have done research and know that most with the 7.3 go with the exhaust from MBRP....I would like to do it that way as well....but nobody seems to know squat about this process....all they want to do is sell me some cheap catback system....that's not what I want...anybody have any suggestions??

EDIT- 5 MINUTES LATER....I just checked- my truck didn't even COME with a catalytic converter in 2002- you would thing that the EXPERT exhaust shops that I consulted would have known that when I told them what I was looking to do-....SIGH....I am surrounded by incompetency....someone help....

IT IS BEST TO GO TO A SHOP WITH THE KNOWLEDGE OF WHAT YOUR TRUCK "REQUIRES" FOR EMISSIONS IN YOUR STATE.....

SINCE YOU NOW KNOW THAT YOUR TRUCK DID "NOT" COME WITH A CATALYTIC CONVERTER.....YOU SHOULD EASILY GET THE SYSTEM THAT YOU WANT.....

ALSO.....IT MIGHT BE BEST TO ASK WHAT THEY WOULD CHARGE TO INSTALL "YOUR" EXHAUST.....AND JUST ORDER THE SYSTEM THAT YOU WANT FROM COREY AT CNCFAB.....

If your truck didn't come with a cat (I don't think any 7.3 has them, could be wrong tho), then you don't need one to pass emissions because it never had one to begin with.

The 4in mbrp is a great option that a lot of people go with. I don't think they're sold in the traditional "cat back" style, but rather turbo back. The down pipe gets replaced in that setup as well. Any shop with any kind of experience should be able to handle that job without a problem.

My old 7.3 had a cat. When I replaced my exhaust with the banks system, you had to cut the cat out of the old system and install it in the new system. It was a 2001. It should say if your truck is cat equipped. Also, emissions testing in Arizona will do a visual to see if you have the cat if it says your truck came with one.

if you get bored, buy the kit, drive up to Phoenix and I’ll give you a hand putting it in... takes about an hour if the turbo clamp comes off easy (ha). I did mine in the driveway. Yours sounds easier given it has no cat.

most obs trucks had cats and CA model 99-03 superduties had cats. If yours is a federal model it would only have a muffler. Go to a different shop that isn't full of crap and support a responsible (knowledgeable business) vs the putz who doesn't know anything outside of bending exhaust tubing.

I once had a shop in CA when I was stationed their through the military try and tell me my 2004 6.0l was illegal because it didn't have the dpf system.... i actually wasted about 10 minutes arguing with him to him finally just realizing only 2008 and newer powerstrokes came with the dpf system etc. I went to a different shop after that and ended up taking my other vehicles to the other shop who was just a better shop overall.

Look at the under hood emissions sticker and see if it states “Federal Emissions” or your particular “State” Look under your truck after your down pipe and before your muffler and see if it has a catalytic converter. If your exhaust is original and it does not have a cat, you do not need a cat.

This is the correct answer. SOME CA model trucks came with a cat but not all - I have a CA model truck with the glow plug module but no cats. Like BTL said, there should be a sticker under your hood by the latch that says "non-catalyst" down the bottom next to the engine size. That should make it clear to the installer that your truck didn't have one.

That said, these places sound like they're full of idiots and I would look for another shop. MBRP is also not the end-all, be-all of exhaust for these trucks, especially for straight pipes - it's just pipe. Flo-pro was the cheapest I found and had no issues with install on 2 trucks now, but there are other options. The biggest decision is mild or stainless steel (I recommend stainless but I have to deal with rust). 4" is the way to go. I went with 5" for the sounds and it's pretty similar to my old 4" - plus the routing was tight over the rear axle and tips are hard to come by.

I hunted all over....under the hood....looked at the sticker on the door panel....I was unable to find anything that said "Non Catalyst"....the only thing that sounded like it might be what you guys are referencing was on the door panel saying "This vehicle complies with all federal safety standards".....I bought this vehicle brand new from Earnhardt Ford in Phoenix AZ in 2002.....the exhaust is original and I jumped underneath and traced the entire exhaust.....it has a muffler....but no cat....

I would LOVE to go to a reputable exhaust shop....one that is knowledgeble, can answer my questions and offer a warranty..,I do realize that there are other name brand exhaust systems and have compared them....the one thing that I like about MBRP is that they offer a lifetime warranty on their stainless system(as opposed to 1yr or 5 yrs)....I am the kind of gal that would rather spend the money up front for a good product that is installed right, comes with a warranty so I never have to mess with it again. I will continue my search for the right exhaust shop that can offer me what I seek....thank you all for your great input...

Thanks for your input....yes, I agree about the idiots....I just don't understand how some places stay in business- supposed experts that seem to know less than I do and although I am not your typical woman, I am certainly no exhaust expert...very frustrating....I realize that there are other exhaust makers, but I am looking to do this ONE TIME, so I would prefer to spend the money up front, get exactly what I want with a lifetime warranty- Thanks again for your input!! By the way, I looked under the truck....no cat, for sure.

the sticker is under the hood near the hood release handle. It will say non-catalyst etc. The door jam wont show anything about it. You can call ford with the vin and they can tell you.

I checked under the hood again- right where you said....no sticker that mentions anything like this in the engine compartment- I am in Arizona, perhaps that is why....the only visible stickers in the entire engine compartment are included below(includes the blank spot where your sticker appears)

I've had 3 7.3L trucks and NONE of them had a CAT. Do the install yourself or as someone offered drive up to them, and they will help. It can be done as a 1 person job but installing the new down pipe is actually a 2 person job or use a piece of wood to hold the pipe in place. One tool you will need if you don't already have one is a sawzaw.

Yes this is looking like the route I will have to go....I was just hoping to be able to be able to go to someone that could set me up with the product I wanted....offer a warranty on both the product and the install.....easy-peazy…..sigh....no such luck...It gets tiring having to do EVERYTHING myself....Oh well...it is- what it is....thanks for the input...

EARLIER YOU SAID THAT YOU BOUGHT THE TRUCK NEW FROM A DEALER NEAR YOU.....

HAVE YOU EVER HAD THE HOOD REPLACED?....FRONT END DAMAGE?....MAYBE THAT IS WHY YOU DON'T HAVE THE STICKER.....

ALSO.....SINCE YOU PREFER TO HAVE A SHOP DO THE WORK.....HOW ABOUT THIS.....

TAKE YOUR TRUCK BACK TO THE DEALER WHERE YOU BOUGHT IT.....TELL THEM THAT YOU WANT TO CHANGE YOUR EXHAUST TO A 4" SYSTEM.....(WHICH THEY DON'T SELL).....AND ASK THEM IF THEY WOULD DO THE INSTALL AND HOW MUCH FOR THE LABOR?....

ONE OTHER SUGGESTION.....TAKE YOUR TRUCK TO A SMALL SHOP.....(OWNER-OPERATOR) AND ASK THEM WHAT WOULD THEY CHARGE TO DO THE INSTALL.....

ORDER YOUR EXHAUST KIT.....AND LET ONE OF THEM DO THE INSTALL.....

Actually I had this truck built to my specs In 02 through Earnhardt Ford in Phoenix.....I drove To Earnhardt in Phoenix from Tucson to pick it up after it was delivered....it is a complete cream puff...hood never replaced...no accidents- have absolutely NO idea why my truck lacks the label/sticker under the hood that people have referred to...I think I am onto a Diesel specialist that sells and installs the Brand of exhaust I seek....otherwise another suggestion may be considered! Thanks everyone for all the help!!

I just found this:
Correct. The best way to determine if your truck came with a catalyst originally is to look at the passenger side valve cover. This is what the inspectors look at here in Arizona when we take our trucks for emissions. "OC" stands for "Oxidation Catalytic Converter". Here is a good link Glossary of Automotive Acronyms .: Articles
