Hey guys

Simple question. I am removing my Titanium Catback and replacing with 1 of these 2 exhausts. The Titanium exhaust is too damn loud and is unresonated so gives bad drone and is causing tinnitus in my ears.

Out of my research, these seem the best options for good sound but with resonators etc. Which of these 2 has a deeper/lower rumble sound and is the quieter of the 2? I am leaning towards to invidia Gemini from videos plus it is 700 USD cheaper to buy for me.

Thanks!

Quieter probably Gemini, deeper HKS.

That's a lot of dough for 10 hp. Is your car FI?

The Invidia Gemini is quieter than the HKS Hi-Power by far. The HKS has helmholtz resonators at the rear (similar to the Motordyne Shockwave) which makes it scream at WOT. The Gemini has conventional resonators/mufflers right before the exit which quiets it down regardless of WOT or just cruising.

Not endorsing nor suggesting but I have a buddy who bought one (of the many) HKS knockoff systems on Fleabay. In his words "best $200 investment made for my car". (This was many years ago.) His rationale: the catbacks make such little power without HFCs or headers and tuning that spending a grand+ for minimal gains is a waste of money. Can't say I disagree.

Again, not endorsing the cheapie systems but it worked for him. It also seems I've heard this from others, maybe on here. Just throwing it out there.
