I love the sound of the exhaust but if your lowered I wouldn't do it. I have the 12" resonated FI and the passenger side rear can got torn apart by something that went under the car at highway speeds at night. The cost for one rear can is so expensive I decided to just go with the Greddy EVO3 exhaust now. Just an FYI.

The FI exhaust doesn't hang any lower than the stock exhaust.

Talking FI System Ordered.......

Hmmmm, never saw all the chatter before I decided, but I ordered the HFC with res, CBE with 18" res, and CF cans......I am chomping at the bit to get it, but I am trying to think of something else.....yeah, it's not working......

After hearing ALLLLLL the others, this was my favorite, so hopefully time sort of flies.....Stillen, AAM, but the FI has me practicing patience..... I am so not patient....

I'll update everyone with the video and outcomes....

3" catted version here chiming in. There's a touch of drone just over 2k rpm, but it is gone by 2500 or so.

It's not how low but what shape it is. I can post a pic if you'd like to see. It will change a few people's minds. I did measure at that location under the car and that area under the car is at a lower point then the stock exhaust in that same location. Overall it isn't lower then stock, but always read between the lines.

Do the ART pipes really help with the drone noise? I don't plan on getting CF canisters.
Still looking for some help with this. Thanks.

From what I hear the CF mufflers give a even more unique sound. If I could do it all over again I would have went with the CF, at the time I felt it was a little ricer.

I don't think the CF canister will change anything except being little deeper and louder.

Check the other thread below. There is a video of 12" CF w/ ART pipes which gave me what I was looking for.

The CF mufflers actually create a slightly louder, slightly higher and more exotic tone. If drone is a concern, you will want to go with our 18" resonators! Please give me a call if you have any other questions, or if you would like to place an order.

Will the 18 res not have drone or cabin vibration? I heard that all FI setups suffer from this.

Of course everyone's ears are different, but in my opinion our 18" resonated system has zero drone, especially paired with stock cats.
