Fast Intentions resonated HFCs installed (vids)

Dynamis · 11-02-2019, 04:24 PM

My persoanl review on this product is that it's pretty damn amazing. I was originally going to purchase a cheaper option, but I was really happy with my current exhaust sound (Motordyne Shockwave) and I didn't want to change it much. So after much deliberation, I decided on these FI resonated. Took about 5 weeks from order to delivery. Great customer service.

Here are some vids. For me, the most important factor was in-cabin noise, and so that's how these are recorded. There's not much to look at, there just from my phone, but they do the job.

Pre HFC early morning cold start

Pre HFC In cabin acceleration

Post HFC cold start

Post HFC In cabin acceleration

The HFCs pretty much double the sound of the exhaust when I'm really getting on it, but when I'm just cruising along, I can hardly tell a difference. There's no hiss on deacceleration, no drone in cabin and no ratteling. I did notice a slight whistle sound when first opening her up each time, though.

Also to note, my mechanic gushed over the quality of the part and the welds, going so far as to say, "These look so good it's ashame we have to put them under the car."

I got for a tune on the 11th, so look forward to one or two more videos. If anyone is interested in more or different views because they're considering these HFCs, let me know and I'll record something.

Congrats and sounds great, but 3 & 4 video appear to be the same.

Nice addition!

I've only had the FI cbe cf option with 18" resonators. Gets TONS of compliments for not sounding stupid raspy but low tone.

Wondering if the HF Cats will retain the same characteristics + a bit louder, and obviously a meaningful power difference?

Yes, our High Flow Cats were designed to maintain the same sound characteristics of the exhaust system while increasing volume and performance.

Your exhaust note will increase slightly. We offer our HFC's with and without Resonators for those who want them. The Resonators further help to reduce interior noise and drone.

We appreciate your review and we're glad that you're enjoying the HFC's. Tuning will further increase your performance gains.

Thanks again!

Right now I have the fi cbe 12 inch resonators. I want to get your high flow cats non resonated. Is there considerable drone with that combo ? This not a daily driver.

I'd recommend our Resonated High Flow Cats to reduce the chance of drone and rasp in the exhaust note.

I now have exactly this (FI RHFC and 18" exhaust) and totally agree. I switched from Z1 HFC's as it was too loud for me, but was pleasantly surprised to retain all the tone, just toned down. My neighbors are thankful, and I am when I actually want to hear music with the top down.

Glad to hear you're enjoying this combo.
