In your opinion what is best exhaust between a hks super turbo (75mm) and kakimoto regu 06&r (80mm) for a near stock ej20? Or are they comparable?
someone use one of these systems?
thank you

Equal length headers or unequal?

Kakimoto sounds very nice for unequal or equal headers

nice low rumble not too loud neither and hks is abit louder depending on if you have a decat downpipe etc

For hks I’m running the hks one piece titanium item on my equal length headers and decat downpipe and certainly cant fault it noise wise or performance much more subtle than a blitz nur spec

Both good exhaust imo through experience

 

For spec c headers and no cat.
Thks for the clear reply

 

I am running an HKS Sport Cat and NUR Spec twin pipes on my WR Ltd twinscroll Legacy.

Fruity.

 

new ear drums required,,,,, lol

 

for reference

my kaki measured @ 130db last week (parked with microphone about 1 ft away )

jdm bug , decat ,3' , twinscroll

 

feckin hell that is loud lol

 

The Y pipe is still resonated.
