The Nissan Maxima was made in FEDERAL and CALIFORNIA specs all the way through 2001. However all Maxima’s starting in 2001 were built to California specs. This was to align to the latest National Low Emission Vehicle (NLEV) EPA regulations.
This just basically means that all 2001 Maxima’s has 4 O2 sensors. Two upstream that monitor A/F ratio and two downstream that sit behind the pre-cats to monitor them.

Finally got a new exhaust made! 3” Single exit with a vibrant resonator and muffler. Going to pick her up tomorrow and I’ll post some sound clips!

This is the OEM Exhaust Manifold Stud and nut found in the cylinder head of all VQ35DE engines.
||Heat Shield Bolts||01121-04871||$3.01||These bolts are used to hold on the heat shields for the stock catalytic converter and pre-cat. Why they are so expensive is a mystery.|
||Catalytic Converter Bolts||01125-03251||$1.25||Bolts to hold Y-Pipe and B-Pipe to the catalytic converter. May be threaded with OEM exhaust nuts 11258-D0101.|
||Pre-Cat Bolts||081B7-0351A||$0.75||On CA/NLEV cars like mine, these hold the front pre-cat to the Y-Pipe. They are very heavy-duty bolts, and I used them in other places due to their length and quality. May be threaded with OEM exhaust nuts 11258-D0101. .|
|B-Pipe Underbrace Nuts||08911-1081G||$0.33||Used in various places. Holds B-Pipe underbrace to car. Also holds B-Pipe exhaust hanger to B-Pipe.|
||Exhaust Nuts||11258-D0101||$1.05||These nuts are used all over the Maxima exhaust. Junctions at B-Pipe/Muffler, Y-Pipe/Cat, and Cat/B-Pipe are all joined with these nuts.|
||Rear Exhaust Manifold Nuts||14094-31U00||$0.82||Being the fanatic that I am, I replaced the rear manifold nuts when I had my Y-Pipe installed. These nuts will not fit on the front manifold in CA/NLEV cars.|
||B-Pipe Extension||20031-0L710||$31.00||The infamous OEM B-Pipe extension. I had to buy this as an interim step when I had the Courtesy B-Pipe installed. This abomination was removed after KOOKS modded my B-Pipe.|
||B-Pipe Hanger||20650-52L00||$13.92||I changed out the hanger when the B-Pipe was installed. It is actually referred to by Nissan as an “insulator” assembly since it mostly damps exhaust vibrations.|
||Muffler Hangers||20650-9B005||$6.81||If you are changing out the muffler and your hangers are looking ratty, it might not be a bad idea to replace them. They aren’t expensive, and all of the hangers are the same. For the rear two hangers you just pop out the interior metal ring.|
||Muffler Gasket||20691-30P00||$2.92||This ring gasket is used between the stock B-Pipe and the stock muffler. I found that with the Courtesy B-Pipe, the Stillen gasket actually worked better at reducing vibrations.|
||Rear Exhaust Manifold Gasket||20691-38U00||$5.16||Gasket for rear exhaust manifold/Y-Pipe junction.|
||Front Y-Pipe Gasket||20691-51E01||$2.76||Gasket for front pre-cat/Y-Pipe junction.|
||Cat Gasket||20692-24U00||$3.43||Gasket for both input and output side of catalytic converter.|
