| Stainless SE-R exhaust |
|
This is another dedicated Street Mod autocross car with an SR-20VE engine swap. The owner of this car had seen the other SE-R exhaust from Chase Race and wanted one for himself. Unlike the other SE-R exhaust, this one is made from 304 Stainless.We decided on Magnaflow mufflers for this project since this owner wanted a low restriction exhaust that was still reasonably quiet. Since Magnaflow didn't have an appropraitely sized resonator available we used a Summit part for this. |
To follow the construction of this exhaust, read below. Click on the pictures to see larger versions. |
| First step, get the car up in the air. You can see the old HKS exhaust here. |  |
| Since we couldn't find flanges with the correct bolt spacing and tubing size for this project they had to be made. They started life as a sheet of 1/4" steel. You can see the cardboard template used. |  |
| After the flanges were cut the holes were drilled. You can see the progression from pilot holes to correct size holes. |  |
| After the holes were drilled the corners were rounded. |  |
|
Since this is primarily a race car, the owner wanted a test pipe he could install at the event. For street driving the car will retain the catalytic converter. With the flanges done, the test pipe was the next step. We started by cutting the appropriate length piece. |
 |
| After it was cut to length, the flanges were welded on. The flanges are clocked at a strange angle to imitate the angles of the factory exhaust. |  |
| With that done, it was time to weld a flange to the resonator and put it in place. |  |
| The test pipe was used to mock up the exhaust because the catalytic converter on this car had one rotating flange. The exhaust needed to be held rigid while it was assembled. |  |
| Now it's time to work on the non-straight part of the exhaust. Start with a 180° mandrel bend... |  |
| ...and make it into two 90° mandrel bends. |  |
|
Add a piece of straight pipe in between them and this is starting to look like an exhaust system. |
 |
|
No, the car is not being held up by the jack stand under the exhaust system. We are using the exclusive Chase Race anti gravity lift to hold the rear of the car in the air. The lack of jackstands or lift posts makes it easier to work under the car. |
