Exhaust too loud

spoolin03 · 12-30-2021, 04:54 PM

The FI 2.5" system seems like the best bet from what I've seen.

The design is very similar to OEM

The flow also seems to be reasonably good

Does this system drone even with the resonators?

The design adds quite a bit of power over stock, but as far as drone is concerned with the resonators, I can't answer that. My FI set up doesn't have resonators. I wanted max power, regardless of drone. My Z isn't my daily driver.

I have the FI lth's with the 12" resonators. There is some drone around 2500 rpm. The 18" resonators take most of it alway. The FI CBE is a true dual exhaust.
