Part Description Part # Price Usage

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.
