- The first steps involve a little prep work. First off, you will need to disconnect the negative (black) terminal on the battery. This simply turns off all of the electronics in the car, as well as resets the car’s computer. Since you will be around electronics, this is a must.
- After disconnecting the battery, use the jack to lift the car up. A good rule of thumb is to have enough room to sit Indian-style under the car. There are several spots next to and around the suspension springs to use the jack on. Lift one side up at a time. Getting enough clearance under the car may require setting both jack stands and then raising each side a little at a time with the jack.
- The stock exhaust system consists of the headers, which bolt onto the cylinder heads. Next is the mid-pipe. The new x-pipe comes in three pieces: the actual “x” piece and then two separate pipes, which will connect the aforementioned piece to the exhaust header.
- When under the car, first you will remove the stock h-pipe. Start this by removing the oxygen sensors from the system. This should require a 22mm socket.
- Next, you need to remove the flange bolts, which connect the h-pipe to the header (this is where penetrating oil becomes your best friend). A majority of cars will have rusted bolts here, so removing them will be difficult. Let the oil soak on the bolt for 10-20 minutes before attempting to remove.
- After removing the header bolts, focus on the air inlet tube connected to the h-pipe. It is located on the passenger side. This inlet tube is what scavenges exhaust gases for the car’s EGR system.
NOTE: In some instances, including mine, this tube will need to be cut for removal. In situations where the EGR system has been deleted from the car, the small inlet pipe will need to be welded shut, as it will cause an exhaust leak without the EGR tube connected to it.
- Next, the mufflers will need to be disconnected from the h-pipe. Remove the bolts connecting the existing pipe to the muffler inlet piping. Once done, the h-pipe can now be removed.
