Has anyone tried this on a Greddy SE V1 dual and had any success?

@Mr-T definitely makes sense, the short stubby ones were some bull shit apparently. The difference came after the longer pipe but not by too much. I ended up with a bad science experiment that'll take some time to remedy... Would you suggest to cut off and patch all 3 of my 1/4 wave resonators?

@ alSpeed2k Mine is a greddy se v1 single. I will have to find an actual source to replicate the T pipe can resonator Mr-T has in exact dimensions and see how that'll do. I imagine it'll cut drone in all rpm range and as attested by previous postings by Mr-T

I may also have a case of blown resonator and backbox.

Northern California hard to find places and good pricing... majority of places do not do stainless OR are HIGH priced. 450-600+ range

I've added a 6" resonator on my HFC which made a big difference when i had my SE dual.

Was it a helmholtz style or quarterwave? I have a V1 dual and been debating adding a resonator to it similar to the V2s.

It was a quartewave that i added to my HFC.

I think I found someone that can possibly fabricate a helmholtz canister but only 4" end caps. What measurements with 4" end caps will end up with the measurements of MR-T's?

Or should I have it a little longer and not worry about it as by nature the unit will cancel out most unwanted frequencies already?

Comparison of my Cleib 70mm with my ASM S-special 70mm

That's pretty much what I added to my HFC lol. Curious to see how the Cleib in-cabin sounds after.

The Cleib sounds amazing above the mid-range, but lower RPM in-cabin drone is pretty bad.
The ASM on the other hand sounds OEM+ and has next to zero drone

licelsior

so even with the resonator added there was still low rpm drone for the Cleib?
