Magnaflow 09-12 Infiniti FX35 3.5L Direct Fit Converter - 5481144Find parts that fit my vehicle

Fits Perfect.

This fit my 1997 Jeep Wrangler with 4.0 L perfect. Some reviews said they had issues with flange being to thick, I have not idea what they are talking about, I easily had an inch or more of threads sticking up to put the nut connecting the manifold flange and the Magnaflow flange.

Great replacement at half cost

This seems to be really well built and costs half the price of the OEM catalytic converters. Cleared my catalytic converter efficiency codes as expected. 100% recommend as a replacement over the OEM part. Easy to install, took me about 3-4 hours because I was trying to do it without dropping the transmission brace but there’s no way around it. If you drop the brace to begin with it can probably be done in 2-3 hours

Perfect Fit worth every penny

Excellent Product.. Worth the money. great quality

excellent cats

I purchased this cat system replacement because my 07 cats were bad, was pretty easy to throw on along with new sensors. we had to cut the old one out, but no problem. new one went on without a hitch, soaked all bolts with pb blast for a few days, and whamoo! new exhaust!! paired with magna flow duel tip street series muffler. sounds great, low rumbel, but not obnoxious. and best yet, no engine lights, been running it 500 miles so far

Fit and finish good.

This Cat is on par with other Magnaflow products that I own. I replaced the Cat when replacing the entire exhaust system. I replaced the O2 sensors as well. Removal and installation of front fender and inner fender took longer than the Cat replacement. I recommend using anti-seize on all hardware.

Fit and finish good.

The Cat build quality is on par with other Magnaflow products that I have owned. The removal of the front fender and inner took longer than the Cat replacement. I replaced the O2 sensors at the same time. I replaced the Cats as I was replacing the whole exhaust system. Recommend using anti-seize on all mounting hardware.

Great Sound and Responsiveness

In spite of a few modifications, it installed well. The quality is very good. It is a bit on the pricey side due to the DMV and State requirements, but other than that, I am very pleased.

Silverado 16 Drives better then ever!

Great product, my original CATS were shot and I installed the magnaflow direct-fit CAT converter and my Silverado is driving awesome. Easy install, you can do it yourself if you have the correct tools and mechanical knowledge. Truck sounds great drives even better. I can tell the high flow CATS have given my truck a little more HP and my gas mileage went from 16 mpg to 19-20 mpg on average. Very happy with the upgrade and I recommend it for anyone with a 2016-2018 Silverado.

Exhaust upgrade

Teamed with headers and new pipes. Easily installed. End result is a perfect for me sounding exhaust.

Cats
