How To: Homemade Race Baffles

[chadthaman]

Also for whats its worth, I am no longer using the expanded metal. I liked the sound but not totally satisied. so I bought generic exhaust pipe. It was 1 7/8 diameter. then used a transition to 2 1/4 at the end that was cut on an angle to fit against the end cap.

One pipe was left straight. the other has several 1/2 inch holes in it midway down the pipe.

The straight pipe is louder with a higher frequency. the other pipe is deeper but quiter.

I have moded these time and time again, trying to get the best sound. Also even though they are piped the way they are, they both have 4stroke race baffeling material in them. It helps keep the outside of the can cooler. If not, it gets super hot.

It's the original size of the factory cans. I didn't cut them down and the cat is still in place.

I have to figure out how to post a video so be patient.

Also the trick is to design each can to the sound or tone you want by trying different inner pipe designs.

I learned that if u want loud pipes u will lean more towards a straight pipe design, but with a few holes in the pipe for some sound absorbsion.

I noticed that a straight pipe is loud but has a higher pitch. The more u allow to baffle the sound from the holes, the quiter but deeper tones.

So I have 2 pipes that are not the same for the best sound that I liked. I used large screws to hold the end cap on the pipes so I could disassemble and redesign the inner pipe and baffle with ease until I was happy.

Also, I just realized that since the last pic I have changed the inner pipes to exhaust pipe with half inch holes drilled in it towards the end.

The pipe in the picture was not loud enough.

It is an extremely tight fit. Making sure you have the spot welds cut, use a slide hammer, and IT WILL COME OUT IN MINUTES.

I stress the slide hammer because I spent an entire day trying everything else and still didn't get it.

That slide hammer will screw into a pilot hole that u drill and will pull it straight out.

It also won't damage the can like trying to pry it out will.

Good luck and keep at it, It's worth it.
