Nice, but does it drone at highway speeds? That is the question.

I would imagine that's what the Helmholtz resonator is for.

I think it may be for only 2017+

Edit: I lied the car in the video is 13-16

It's 3" piping, so I would assume that it does have some drone.

That doesn't always help. It basically shifts drone from one rpm range to another. I think the V1 of this exhaust also had a Helmholtz resonator but reports were that it droned like crazy. I was just hoping that the change to this style muffler from the canister style would help a little.

Ah yes, I ignored that 75mm part. hehe Oh well poop.

Yeah, I really wish that HKS would make these designs in 2.5" instead of 3". Would be a lot more tempting! In fact I would've already ordered the V1 if it was 2.5".

Cat backs are the same. Only the axleback is different for 17+

Anyone know the weight difference between the V1 and V2?

I'm quite happy with the V2 system with stock headers. Drone is not a problem IMO. Did a little research and found that the V1 weighs 25.6 lbs while the V2 weighs 28.4 lbs. That compares to 39.7 lbs for the stock system.

Sorry for the revival but I’m suppose to pick up a v2 tomorrow and I didn’t realize the seller stated 2017+ but I have a 2014.

Can anyone confirm that it is/isn’t compatible with my 2014.
Please and thank you.

Should fit okay




Here is a vid if anyone whats to hear. This exhaust is LOUD AF with one cat setup but tame when not pushing the gas hard. I have a friend with one :)

Not my car:

Great exhaust, here is my setup with JDL UEL catted headers. https://youtu.be/ZhQ3JrpU7ZM

Are you running a stock or aftermarket front pipe?
