  3. Tomei includes some "bolt-smooth-paste" to help with the install. Liberally apply this to all clamp bolts, the bolts & nuts, and the exhaust hangers. We also got some red loctite to keep bolts from backing out. A little goes a long way.

  4. You can bolt up the exhaust before removing the old one to save some time while the car is on jack stands. When bolting, we tried to install all clamps with the bolt head facing down to make it easier to access. For nuts and bolts, we typically try to have the nuts installed pointing toward the rear of the car when possible. You can always adjust it as necessary for easiest access.

    • The spring tensioners should be installed with some pliers.

  5. Once the car is on jack stands, find someone (or use your jack) to lightly support the exhaust. Disconnect the exhaust from the catalytic converter. Next, unbolt the midpipe from the hanger bushing it is screwed into.

    • Once the last hanger is out, the exhaust should just drop to the ground (hopefully slowly if you supported it).

  8. At this point, you can just install the next exhaust reverse of what you did to remove the old one. Since we had time during this write up, we wanted to compare the exhausts visually, check their weight differences, and see how clearance differed.

    • Keep in mind, this 240sx is lowered on coilovers, so your clearances may be different. This is just for relative reference.

  11. The Tomei exhaust has approximately 5" ground clearance at the bottom of the rear muffler. There is approximately 4.5" clearance at the lowest point of the exhaust. Finally, we clear the stock tow hook by about 0.5".
