single exhaust choice ?
#22
I believe HFC allows most drone in exhaust systems....
Berk 3" single (catless) for all out performance/dollar
Evasive EVS 70SSP (w/ TP) for balanced performance/noise - cheaper than ASM and readily available. It's basically a ASM siren circuit replica but in 70mm form.

There are no single exhausts that are drone free (especially in 70mm). Even the ASM will drone with HFC or TP since since it is designed to be used with the stock cat. The ASM siren circuit is a 60mm single exhaust. Unfortunately the ASM 70 is impossible to obtain new, and probably Very difficult to get used.
I never felt the EVS70 was extremely loud (when I demoed Daryls car) and the Berk is Definitely louder in comparison. In comparison to the OP's listed exhausts - Apexi n1, I am sure the EVS is a much quieter exhaust.
Btw, this is a Siren Circuit that the EVS is a 70mm replica of. The real thing cost over 4 grand.

i think i'm stuck between the HKS and the Berk.
i kinda like the HKS more, it looks nicer and sounds a little better than the Berk. it's not a big difference in price but i think i'll go with the HKS !
thank you guys very much !

That's not true at all. Any dyno where the power went down from a single or freeer flowing exhaust is because it lessened the rstriction which in turn lowers the boost a little bit. Once you pulley down to make up for the boost you will make more at the same psi.
OP any of the singles will be very loud! Especially with a supercharger! Drone will be fairly extreme as well. I have a greddy spectrum elite dual and even that is quite loud with lots of drone with my sc setup.

Because the larger exhaust freed up the system and lowered the boost a little bit I'm sure. Once you get back to the same psi you will be making mo power.
