Here is a video of cold start up. It is a horrible day out so pardon the wind.

It would seem to me that the header tape will still allow sound waves to permeate and you've created quite a cavity there. If I were you, I'd seal that area up better and drive around before you weld it back. You may want to cover the tubes with something more rigid and sound reflecting than the header wrap.

If you guys can come north a bit, maybe I may meet up too..maybe get out of the city and work it into a nice fall drive! Its too far to go to LI for a quick meet for me.
I couldn't use the exhaust header wrap because it was too thick. It is very tight between the two pipes on the left side of the photos. I used exhaust/muffler repair wrap. I still had some exhaust coming out of the chamber on the right (as installed on the car). I will be securing the wrap with stainless steel tie wraps. When the wraps gets hot, it cures and seals better. I think I will re-stuff the chambers with the absorption material too.

Perio, the vids you posted are private. When I click it it says you have to add me as a friend on youtube before I can watch.

Cant wait to see how it turned out! Great work and effort, man

They seem quiet on the video but they are VERY loud.

If the weather clears up, I can get better video.

OK, Change of plans. After yesterday's test run, I decided to unwrap the two smaller exposed sections. I think the system needs some absorption. I clamped down the wrap on the pipes that have the larger amount of perforations. I'll re-stuff the chambers with absorption material and see how it goes.

I just finished the videos. I think I got what I was looking for.

By keeping the smaller set of perforations and re-stuffing the chambers, the exhaust is still MUCH louder but not insane like it was before.

Videos are processing as I type this.

Here you go... I recorded at different angles. I noticed that the recording sound changes a lot when the camera is in different locations.

Dude that sounds really good IMO! Good job! You gotta do a final summary of your work. Judging by your plates and your name...I'll take a shot in the dark here. You're a Periodontist?

Sounds a bit too much like a pushrod V8 at certain angles and rpm, rather than the technological marvel that it is, but surprisingly, better than most aftermarket exhausts I've heard. Not bad for a relatively simple procedure .

Hey, better loose the duct tape if you plan to take it for a ride man; you'll never be able to remove it afterwards. Good job. Curious about the volume/drone inside the car. Keep us posted.

It is hard to truly represent the sound via video. I guess it has to be heard in person. Of course I need to get videos of it driving. I am going to weld it shut first so I can get rid of the tape.

Nice work, it's always cool to try different things.

Hope to see a driving video soon.

I removed the unit from my car and sent it to be welded. I will post new videos once I install it on the car.
