My test pipes I bought from eBay are resonates and make what some call bees in a can noise I just wanted to see if there was any resolution to that

 

Install resonators. More if you already have some.

 

Are they circuit werks? After installing them with my Ark catback I get a tin can rattle type sound at 2500-2800ish rpm that sounds horrible.

 

Same ones I got. Sounded good when I heard another member's set-up with them on. Installed myself and my car sounded awful. Installed another set of resonators on the Y pipe (four in total) and made a huge difference.

 

Circuit Werks has two versions, I had the anti-reversion one and with my Top Speed exhaust and Motordyne resonated y pipe, it was deep and I never had rasp.

 

I have the anti reversion version as well.

 

Anti reversion model was paired with my top-speed Y back and the rasp was insane. Took two resonators to bring it back to a tolerable tone.

I actually got mine after watching your build panda. Mine didn't sound anywhere near as good as yours.

 

that’s crazy because two other guys locally that followed the same setup as me had good results also. That’s with the Motordyne resonated y pipe.

 

It seems the motordyne pipe is the missing piece to the puzzle. I also bought these pipes after your reviews panda since I couldn't find any other info on them.

 

I had a good experience with them and was about to buy a second set for my Z1 headers. I ended up finding some art pipes for a steal.

 

Bingo...
