We'll investigate the prices for this thing and will show you some ways to sell it at a better price. Today, we'll tell you whether you can sell your Nissan Titan catalytic converter for good money. But the biggest problem is actually the decision on what you should do with the old converter to get more revenue and cause less harm to nature. To replace a cat converter in the Nissan Titan is not a cheap task. This truck would have easily made over 300+whp with the factory sized tires.With an old catalytic converter in your hands, you may be thinking about some additional money to compensate for your big repair bills. Looking at 5k you can see we gained 40 wheel torque and almost 40 whp. Peak power on Jason’s truck came up nicely. WOT started after 3800+ RPMs so ignore it before then on the graph. This in turn hurts performance (f-ing duh!). Not only are they heavier but he loses a ton of gearing too. It took two of us to put his wheels back on. Jason on the other hand had his Titan lifted and equipped with massive monster truck tires. Brian’s truck was not lifted and had factory sized tires. Your probably wondering why Jason’s truck baselined ALOT lower than Brians. We also installed a set of Berk’s HFC B-Pipes for even less exhaust restriction. headers was NOT having to extend the O2 sensor wiring like we had to do on the Stillen units. Where’s Doug? If you take a close look you can see the D.T. had cleaner ports than the Stillen pieces. The new shiny ceramic coated header is from Doug Thorley. This however does not help manifold longevity. One reason they do this is to get the cat hot quicker and keep the cat hotter for cleaner emissions. Here you can see how the factory tied the factory manifold (TOP) in with the main cat. Sadly though, the dealer will try to pass it off since its a hard job to do (replace manifold) and hard to see it while on the vehicle. By law or mandate, Nissan and other car manufacturers are responsible for replacing this part since it deals with the cats (emissions components). I took a picture of what came off of Jason’s Titan’s manifold. Almost 80 wheel torque gained and 60 whp! Not bad for only headers and tune. You can clearly see the the cursor at 4250 showing some sweet gains. Peak torque shot up over 59 wheel torque. Although peak WHP wasn’t crazy the gains throughout the band were huge. You can see the AFR on the blue run was bad. To fully appreciate the headers a tune is a must on these engines\trucks. Red run was after we tuned the Titan for some excellent gains. Blue run was after we installed ONLY the headers. It wants to downshift as soon as one goes WOT. What a joy installing headers on a 4wd truck.ĭynoing the Titan is a tad tricky due to the AT transmission. Pic from below of both headers installed. Somewhere in that picture is the Stillen Header. Up first is Brian who brought in a set of Stillen Headers for his Titan. Since the manifold and cat pipe are all one piece there ends up being a tremendous amount of stress on the manifold due to in part by the weight on the manifold and thermal expansion. One problem that plagues all Titans is the factory exhaust manifold cracks.

Brian and Jason both brought in their Titan trucks for a header install and tuning.
