That is the most simple version I've seen so far. Thanks! Sounds like just about any configuration that's roughly 32" long will suffice. I found some mandrel bent stainless at summit that's priced well. I'll mock it up then take it somewhere to weld it.

 

30" is the length of the resonators in my picture above. This eliminated the really bad drone from 1800-2000 RPMs. There is a very slight drone remaining at 1600, but it is nothing compared to what it was before.

 

How did you come up with the 32"?

Did you play with the length at all on the 5 builds or do you just do a standard 32" pipe

 

I had shorter ones on my truck on the first try (like 24") and they helped. Someone said they heard 32" was the magic number for a V8 at 18-2200 rpm, so I extended them and was even better. So I've just been building them at that length on everything I do and it's worked on all of them.

 

Thank you Sir, I appreciate the feedback!
