Invidia Gemini vs HKS Dual Hi-Power exhausts

Amuse370z · 06-21-2011, 07:01 PM

At first I was thinking of the Gemini because of its fantastic reviews, looks and price.

The HKS exhaust is about $1000 more than the Gemini, I have some spare cash to spend and I can't decide whether the the HKS exhaust will be worth it.

I don't want the exhaust to be too tamed but I also don't want to get pulled over, will I have an issue with the HKS? What about HFCs? I don't want to deal with emission problems. Will an Invidia + HFC be as loud as the HKS without?

Here is a video of my Stillen G3s/Motordyne M370/Berk HFCs/HKS exhaust on the dyno so you can be the judge of sounds.

I have Gemini with ATP pipes and my exhaust is 20-30% louder then my previous FI exhaust which was on stock cats

I just have this small clip hope it helps

Docaam: How long have you had ART Pipes with your Invidia? Any issues with the flex section? I just had mine installed.

My friend Wheee! has an HKS exhaust and it sounds good with Berks HFCs. That setup compared to my ERZ HFC and Invidia Gemini are about the same in loudness. Personally, if you were buying new, I don't think the HKS is worth paying an additional $1000. You could use that money to buy more mods. However, the two exhausts look different from the back, and if you are wanting a certain look, then that's going to influence your decision as well.
