[WTB] Aftemarket Catbat / Axleback Exhaust
My recent Canadian experience, i went through all you said.
I did consider everything from simple washer mod, ebay axleback /catback, AAM short tails , and Stillen and F.I catback.
I ended up with Invidia Gemini, and am still happy with my choice.
One thing to note is i was looking for a quiet system; no drone and not too loud.
1. I crossed Stillen & F.I. off my list, only because it would be around 2.5k CAD.
There is no official distributors in Canada, so the price almost gets doubled when they get here. invidia gemini is around $900 in the states and I paid $1345 CAD tax included; reasonable considering the exchange rate.
2. Ebay axleback / catback exhuast (J2, Topspeed); they got fitment issue, and stick out too much (beyond the bumper) for non nismo 370z.
3. AAM Short tails Resonated & Non-resonated; way too loud for my taste. They are basically muffler delete, and will have some drone.
4. Washer Mod: People have reported decrease in performance; throttle response, and torque at low rpm
Invidia Gemini will be for you IF
1. you are not looking for performance gain -> if so, look into F.I. (forum favourite) or Stillen (not too loud, but heavier with similar HP gain)
2. Looking for a slight increase in sound volume
3. Not loud system, you can make it louder with HFC, but people have reported some issues when mated with HFCs or test pipes.
