Easy installation, long-lasting durability, and better protection - these are just some of the listed features of an EvanFischer catalytic converter. To find out if it will stand true to its promises, we've installed a new EvanFischer direct-fit catalytic converter on our 2000 Nissan Maxima GLE and had it go through the usual stops of a DIY installation, rigorous test-drive, and a smog inspection test.
- Direct-fit replacement with powdercoated silver finish
- Fitted with an aluminized steel heat shield
- Catalytic case made of high-quality and durable stainless steel with 16-gauge aluminized steel tubes
- Includes all gaskets to be used for installation
- OBD-II and EPA compliant; 49-state legal (no CA shipments)
- Comes with a 5-year or 50,000-mile limited warranty
- The EvanFisher catalytic converter looked great with the coating, especially when it was installed under the Maxima. It matched the rest of the exhaust system, and it looked like the catcon came as a set with the car's exhaust.
- Upon our initial test drive, we noticed a bit of an increase in the Maxima's power. Although it was not a considerable improvement to be called consistent, it was enough to let us know that the catcon worked well with the rest of the exhaust.
- After a week of installation, the 2000 Nissan Maxima GLE was taken in for vehicle inspection. The vehicle passed state inspection with no problem, ensuring efficient air flow from the catcon.
- Installation can be a bit tricky for this replacement part. Although it indicated a direct-fit design, it was not comparable to the specifications of the original part. We had to cut the welded bolts and reweld it together to make it fit into the vehicle's muffler pipe. The EvanFischer catcon's bolts were about 2 to 3 inches shorter, which made the whole installation process a little more tedious.
- The heat shield that came with the part also proved to be a problem during installation. It slightly interfered with the bolt. Although this was not much of a problem as compared to the welded bolts. We simply used a different socket to tighten the bolt.
- The new catalytic converter did not come with new exhaust manifold gaskets and flange gaskets. Since these gaskets are more likely to be damaged during the removal of the old catcon, it would have been convenient to have a new set of gaskets with the part. We had to buy the part ourselves, which halted the entire installation job for a few hours.
The main cause of concern for an EvanFischer catalytic converter is its fit. Although the part is described as a direct-fit replacement, it does not fit like an OEM catcon as would have expected. This is not a huge thing, though. If you're fine with spending a few more dollars on a mechanic that will modify the part and correctly install it to your vehicle, the better air flow and slight increase in power could be a win-win trade off.
