DIY AP1 Single Exhaust Cap Installation

Many owners are upgrading their exhaust system with a dual or a single exit exhaust. Although the single exhaust option will give you higher performance, there is a small sacrifice in the looks of the car’s rear end. However, there is an option available in the market for MY99-03 to fit a single exit exhaust gap cover. This time we would like to thank CA_S2K for the following DIY write-up, which will make your life much easier if you decide to go ahead with the installation.

Today I picked up a single exhaust cap in carbon fiber from Heel Toe Auto.

I noticed how some people get confused with a single cap. Thinking they have to cut out and replace the bottom piece of the bumper.
That is not the case, it is a “cap” the fits flush right over it.

Time took for install-25 minutes.

The cap comes with (1) Alcohol swab (2) Tapping screws and double sided tape attached to the cap.

My Z-Tec single exhaust cap got warped because my T1R exhaust decided to have a mind of its own and thought it would adjust itself closer to my bumper. So I picked up a Spoon N1 instead.

After taking the Z-Tec off I had to use a dremel to cut some of the melting plastic off the bumper. As I was taking the cap off, I broke the oem tabs, so instead I used nuts and bolts for installation.

On to the install.

Make sure to clean the area thoroughly with the alcohol swab for the tape to adhere.

I had extra APR nuts and bolts so I used them instead of the oem tabs.

I then loosely attached the cap from the bottom.

I then peeled off the double-sided tape and attached the cap as flush as possible.

When I was satisfied, I used the tapping screws and drilled them on the ends of the cap.

Tighten everything down and thats it.
