WalkerExhaust Ultra EPA 54782 Direct Fit Catalytic Converter

Direct fit, not noisy when driving and no check engine light. Only missing heat shields.

Direct fit, no issues there. Comes with a warranty card you fill out and send off in the mail. This is lightweight and not as large in diameter as the Original OEM rear cat that was on my 2008 Nissan Altima Coupe (manual trans). Car does not sound like it originally did, it has a metallic clicking of sorts that goes on when accelerating (when the thing is heating up). Overall, not sure I would buy it again but it has been around a month so far --- no check engine lights or any issues besides what is mentioned above. 4/5

Good value and good quality and good fit

So I got this test pipe for my 07-12 Nissan Altima 2.5 easy to replace under the vehicle has one oxygen sensor in it and 3 bolts on the front and 2 bolts on the rear and it fits perfectly no issues with the parts and it does the job the dealer wants 7 hundred for the replacement part you don’t need the dealer part here’s one that does the job and you saving money

I cannot tell you how doing it yourself is the best way to go. To install this fairly easy converter took about 3 hours. Now that I know everything to do it would only take me about 1 hour to install. I was told by Nissan dealership that it will cost 1700.00. I was also inform by a local muffler shop that they could do it for 900. Automotive shops are a ripoff and I feel sorry for people who do not know they can do this on there own. Put that money to something else more important. It cost me this part + 5.00 the gasket. I went to AutoZone and rented a oxygen senor socket set and it was free when I returned it. I used a little socket tool kit that I got from target to do all the work. Park works as intended and service engine light is off. Vehicle has a little more pick up power as well. Remember to take your old one to a junk yard or scrap metal because they will pay you for the old part. Not much but hey something is better than nothing.
