Perfect fit! Heavy metal pipe and perfect welds! Easy to install!!! Would recommend!!

I bought my son’s truck without cats and replacing them in a shop was way too expensive. We bought these on the recommendation of his auto shop teacher! His teacher helped him install them in class, they are a great fit and his truck is so much quieter. No more gas smell or waking the neighborhood on his way to school and work! Would definitely recommend!

bought this twice & its done the job both times

FOMIUZY Catalytic ConvertorThe product receives negative feedback , bad quality, truck broke down and product turned black and looked burnt and sounded bad after a week, by the time you get it installed and find out its faulty and after the fact your vehicle stops running you may want to try getting a refund or swap out the bad part to the company, in this case FOMIUZY, which had told me there are no guarantees or warranty's. That they are an auction house not a dealer of any certain thing they sell. That these are returned items with no guarantee or warranty. Amazon stated since I did not contact them about this before the 30 days there is nothing they can or will do on this product do to their 30 rule. I let Amazon know I feel scammed and even called Fomiuzy, as I was told to by Amazon to do the state on the order there is a life time warranty towards the bottom of page. Fomiuzy let me know they do not return or have warranty that Amazon is aware of this and they don't have another to send , that customers have been calling them due to Amazon giving out their phone number for life time warranty. Seller states Amazon posted that he did not. Amazon stated after 30 days they do not honor products sold on Amazon and there is no fraud dept to report to then they proceeded to tell me they could no longer speak to me on this. I called Amazon several times at the shock to it and no Amazon does not play around they do not help customers once 30 days is up, they also told me it was not considered a scam. FYI I lost my money on this and there is no longer a department through Amazon that has pity on a pure buy it is what it is lost money, I feel scammed and frauded. I was also told that since FOMIUZY does not state the product work or doesn't work then it's not fraud, how can that be? The FOMIUZY REP or Owner said they so not specialize in these products they are a auction house that sells things people return for one reason or another. *Warning sign with red flags waving I feel duped and sad, please watch out for this and if you don't honor the 30 days call in with Amazon you will be stuck with a nonreturnable product(s) and a none running car. ~ Food for thought! Why is FOMIUZY selling me a product with the uncertainty of maybe it will work maybe it won't approach, and they are just an Auction House? Yes, Amazon does allow sellers to list and sell products that are in a used or "used/very good" condition, which could include broken or damaged items, according to an article on AMZScout. However, they must be accurately described as such, and in this case, it was not. Amazon does have policies in place to address returns and potential claims for damaged items. But in this case, it does not they said 30 days is up, we are going to hang up after I had called Amazon about 5 times.

Flanges was not quite the right angle, but really torque them down and got them to seal up ,crossover pipe not quite long enough to use the exhaust clamp provided Ended up welding that joint all in all check engine light Didn’t come back on , notice a difference in how truck idols and accelerates so far so good

Fit perfectly. Needed a new gasket O-ring for driver side piece where it meets with the collector as well as the triangle shaped gasket . $10 and done overall well worth the money saving thousands!!

It fits and works well, my complaint is in the o2 sensor threads. They don’t quite line up exactly so the sensors are at weird angles.
