Very Pleased

Had a P0420 code on my 350Z (VQ35HR) after installing HFCs. I installed the 90 degree mini catalizador. Cleared the code with an OBDII scanner. After ECU tested the catalytic converters, the code remained gone and car ready to pass the state smog test. Mini catalizador did what it was supposed to do.

Absolutely Works

They are pure genius! My check engine light went off immediately! A mechanic friend of mine told me about them after he said they never failed him. They replaced having to get a new, pricey catalytic converter. Highly recommend! They are pure genius! My check engine light went off immediately! A mechanic friend of mine told me about them...

Engine light be gone

I was troubled with a p0430 code for years. Installed this on bank 2 sensor 2 and boom code has not came back! Much cheaper than a catalytic converter. I was troubled with a p0430 code for years.

Great quick

I admit I was skeptical, but I was so wrong! This adapter is the real deal. I’d been driving with a check engine light that had a mind of its own. After using this, it feels like my car finally got its act together. Smooth rides with no more worries about sudden breakdowns, and I’ve even noticed a slight boost in fuel efficiency. Count me impressed! I admit I was skeptical, but I was so wrong! This adapter is the real deal. I’d been driving with... I admit I was skeptical, but I was so wrong! This adapter is the real deal.

Save on catalytic converters

I don’t typically leave reviews, but this spacer truly deserves praise. My car was a wreck—check engine light always on and performance inconsistent. After installing this spacer, it feels like a brand-new ride! Smooth acceleration and no more annoying lights—it's a dream come true. If you’re facing car troubles, invest in this spacer; you won’t regret it! I don’t typically leave reviews, but this spacer truly deserves praise. My car was a wreck—check engine light always on...

It actually works!

I have a 06 Matrix after using spray valve cleaner I got a P0420 code. I changed both sensors and used multiple bottles of cat cleaner. Spent hundreds of dollars with the light never going off. The car ran fine 30 MPG no soot. I installed this product 2 weeks ago and cleared the light. It has never come back on and no pre code when I check it. I wish I tried this first!

Saved me money and time!

This part saved me so much! The upstream O2 was not working properly but I did not have the tools or money to get it replaced. I was able to use this on the down stream O2 sensor, that's easy to reach, and get my car smog checked and pass! Thank you so much to all those involved making this part and saving my low-income self from losing lots of money!

Excellent Products!

I am so impressed with your products--nothing has worked to rid my car of the dreaded CEL light until now. I ordered the mini-cat 45-degree sensor spacer, and the 90-degree. Product is wonderfully well-built, and totally adjustable for fit. I found the 45-degree cat spacer fit best for my extremely tight space (2016 Cadillac ATS). Love how it fits, and how it works--no more CEL light!! Thank you for your fine products--you are an amazingly good company in a sometimes-shifty industry. I am very grateful for you!!

Impossible made possible

I was working on a 2004 Honda. Accord that wouldn't pass smog. the car came to
me in poor running condition. It had no power. To take off from a intersection you needed a head start. I discovered that the converter was plugged almost solid. I decided to cut a small hole to see if it ran better and it did. I gutted the cat and put it back together and it ran great. Now my thoughts were to buy a universal cat and be done with it. Well that did not go as planned because the state I live in banned universal cats for import cars and you had to get it from the dealership and the dealer wanted almost $2000 I was searching the net and ran across the Mini cat. I did not think it would work. But what the heck it's worth a shot so I ordered it. The cat was just a shell after I gutted it. I put it on and decided to try smogging the car. Well to my surprize the car passed smog Thanks to the Mini Cat....

Excellent product

I will recommend it 💯 %. I bought this for my Chevy Cruise 2014
After I dis change the Catalytic Converter twice, the only solution to turn the check engine light was this product.
Fast delivery.
Good Price.

Works as designed/money saver

Very pleased with this product. Installed on a 2005 Jeep Liberty pushing 296k miles. It needs catalytic converters but they cost as much as the Jeep is worth. CEL is off, adaptive fuel values back to normal, idle seems a bit smoother, and a bit of improvement on the mpg’s. I have 15 plus years of experience in the automotive field and do approve of this product. It is a lot of help to people who have older cars and trying to get by in this crazy inflated economy.Ultimately a big Thank You to the inventor/owner of mini catalizador company. Really for thinking of us folks who just cannot quite get that new vehicle or repair the old one we got fully.

It WORKS!

Had the 0420 CEL code on my '09 Prius after installing an aftermarket converter. Not only did this unit clear the code, the 90º angle solved the clearance issue between the O2 sensor and the car body. Money well spent!
