This is a simple tutorial on how to get more horsepower using the stock exhaust.
One of the easiest ways to get some free horsepower from your stock engine on the HPI Baja 5B is to remove the stinger and the baffling from inside the exhaust can. Its truly an easy task and the rewards plentiful.
I first removed the stinger off the HPI Baja and noticed a large difference in the low end. Once I removed the baffling, I was amazed at how much more ponies went to the ground. You can choose to do One or both mods depending on your needs.
Parts:
None
Optional parts:
- Needle nose pliers
- 3mm Hex Wrench
- 4mm Hex Wrench
- Screwdriver
- Blue Locktite
Time:
15 Minutes
Skill level:
No Brainer
The first step will be to remove the stinger mounting bracket with a 3mm hex wrench
If you are only removing the stinger, cut the zip tie and gently pull on the pipe till it comes off. You may want to call it a job done and go see what you think. Honestly, take the additional 10 minutes and remove the baffling from the can. It’s time well spent.
If you are going to proceed forward, you can just swivel the pip around and remove it later or do it now. Doesn’t much matter. There are 2 4mm hex screws that hold the can on. Go ahead and remove them.
The can should easily come off with a slight pull. Be careful of the gasket. If it gets ripped or torn, replace it.
Remove the stinger if you didn’t do it earlier.
Now comes the fun part.
Inside the can on the exit port side is some wire mesh and baffling material. We need to remove everything inside the can. I’m sure there are many ways to do this. I found by using a screwdriver and rooting around the inside of the can from the intake side loosened everything up. From there I used a few different needle nose pliers to pull everything out. It took a little work but I eventually got it all out. You need to keep peaking inside to see if you got it all. If you have some kind of bent hook or pick it may work just as well as a screw driver. Look at the tools you have and work with them.
Even my dog took an interest in this one.
You will want to rinse the can out with fluid of some sort to be sure there is no particulate matter or chunks inside. You can also use compressed air if you choose but a fluid is recommended.
Go ahead and reinstall the can onto the HPI Baja using the two long bolts. Be sure to use blue locktite on them or they may back out. Now go out and run your beast and let me know how you like your FREE Power.
