no, there is 3 options of resonators that you can choose from. also remember the real drone comes in when you delete the cats.

FI OPTIONS:
high flow cats w/ resonators - least power gain & least volume/drone
HFC/no res - low drone decent power
test pipes w/ res - good power slight drone reduction
non-res test pipes - most power/most noise
long tube headers -

CBE:
18" resonators - least drone, slightly less ext volume
12" resonators - small drone
no resonators -

on a sidenote pretty much any aftermarket exhaust there is going to be some drone at some RPM its kinda how sound waves work and if you want to add some power/volume you cant be a little bitch about a bit of in cabin noise. its a sports car, its how it should sound.

i have the non-res CBE w/ CF mufflers and non-res TPs. also i have my set of FI straight pipes.

Thanks! So for least amount of drone just get the 18" resonators?

CRiZO

Resonators are purely cosmetic. Their only job is the modify the sound. The HP difference is essentially nothing.

FPenvy

least drone would be stock cats and 18" resonators.

i do not know if you planned on swapping out the stock cats or what your gain goals are.

i was speaking to the HFC aspect of still being restrictive and killing some power.

yes, resonators dont even drop exterior volume at all either. they primarily reduce in cabin drone and smooth out the sound.

I was planning on keeping everything stock and add an exhaust that can work for my daily highway commute.

How would you rate the 18' Resonator Fast Intentions vs Greddy Evolution GT?

FPenvy

personally, i think FI is the best 370 exhaust on the market. sound, power, quality, and customer service.

Greddy makes good products as well. the evo gt is a good system i just dont think you need 3" on a Z without turbos.

I rarely agree with Frank, but he’s spot on here. 3” is probably overkill on a basic TT setup. You’d only get a restriction if you are pushing the limits of the stock block or running corn.

I have heard both in person either will have drone but the FI exhaust with 18” resonators will be louder though. Both the FI exhaust and Greddy Evolution GT exhaust have excellent quality and fitment.

Sales@F.I. Inc.

Fast Intentions is definitely a popular favorite with over 1,900 units sold for the 370Z.

Please let us know if you have any questions.
