HOW TO make your exhaust LOUDEST
*STOP the comments on how bad the welds were. I know they were shit. Take a look at the rust I was welding on. This was one of my first times welding. I didn't know you had to get the welding surface to bare metal back then. Also, I was working with a 110 harbor freight welder.* This is a video on how to make your Exhaust straight piped but still look like you have a muffler. WARNING: Doing this mod may make your vehicle not pass inspection or emissions. Keep that in mind if you want to make your Exhaust straight piped. Check out my YouTube channel for other how-to videos and other Exhaust videos! My vehicle is a 1991 Toyota 4Runner with a 3.0 V6 5 speed. Lifted 3" with 33s. Feel free to comment with any questions.
