exhaust tone in person
 

So one of these day im gonna buy the fi hfc and cat back with 18" res. My question is i have heard many examples on here and you tube. But i have never heard one in person. Is it a big difference is person to what they sound like online. Of course it sounds better but i am wondering how so? Tone, loudness, rasp? Thank you

I have the FI exhaust with 18" resonators and stock cats. After watching the videos and audio clips of the exhaust, it was louder than I expected when I experienced it in person for the first time. Not in a bad way though. And the tone of it matches what you hear in the YouTube clips.

beautiful. i love the tone was wondering about the sound. Since i am getting the hfc do you think i should get the 18" or the 12" res. I want people to hear it but i do not want overpowering and i am not a fan of a lot of drone on the highway. I had a bassani exhaust for my svt and it was loud, drone was rediculous, dont want that again.

I'd go with the 18" resonators then if you want to minimize drone. Especially since you're going with hfc's. You should give Tony at FI a call. He's a good guy and will be able to advise you on what you're looking for.

ya i'v pm'ed him a few times I know hes busy dont want to waste too much of his time ill do my research save a few more bucks then just call him and place the order. Did you notice a difference in power after the install? thank you sir

No problem. :tup:

Tony just installed my F.I. w/ 18" res. last weekend (still have stock cats). I too was wondering this for a long time before purchasing.

Fit, finish and craftsmanship are second to none. Although not fully broken in, my first impression is that it sounds great but I was a bit surprised at just how deep and loud the "quietest setup they offer" actually is in person. This is by no means a negative comment, just unexpected. Tony and others tell me that this system settles down a bit (~15%) after a few hundred miles which is typical of most performance exhausts. Between 1.5k and 2.5k rpms the system seems to be at it's deepest and loudest in the cab. There is a slight hint of what some may call a "drone" as you pass through 2k rpms, but it comes and goes quickly and is completely tolerable for me. As you approach 3k rpms it turns turns into a symphony of automotive performance and I find myself revving higher than before. No rasp. The tone is deep and smooth.

Well said and I agree completely.

niiice i can;t wait to get this bad boy online it sounds so bad ***. What about the gains in power was it easy to notice?

Haven't noticed any gains yet on the butt dyno, but I have been taking it easy during the break-in...no WOT runs yet.

I should also note that on my 3 hour drive home after the install, freeway cruising was completely tolerable. You can sense its there with the stereo on but it isn't overpowering.

thank you for all the info sir exactly what i wanted to hear!

I didn't really feel anything on the butt dyno either but it sure does sound mean at WOT. People have seen increases of about 20 hp with the hfcs and cbe together.

i have HFC and CBE 18" res SS cans. after about 100 miles on the highway it quieted down some but was still pretty loud. i am at 300 miles on it now.. wot sound crazy lol so good... i get nothing but compliments on it. i wander now though what it would sound like with the res cats since its still pretty loud.

so you need to get the hfc and the cbe to get the 20hp increase . I taught if you add the cbe you get the 20hp increase.

I think 20 hp is a stretch for just the cbe alone.

jay
 

so whats the hp gains with just adding the cbe

from what the video and dyno chart on their web site its about 20 from the CBE alone and about another 5 from the HFC.Tony can clarify that for you though

I am a big fan of the screen name! I am a big mustang guy myself.

I know that you have gotten a lot of good advice from the other members here. They are all great people and will give you positive feedback.

Now at the same time if you have any questions at all or would like to place an order, please do not hesitate to call me directly...

Thank you, Tony

No, the vids on youtube are VERY close, except in person the tone is actually a little bit deeper and better.

I personally have the 18" resonators and SS round mufflers. Just recently purchases resonated cat pipes which I will have a huge review writeup with vids very soon...once all the snow is gone that is!

Tony, I will call you soon I am def goign to buy that set up saving up a few more bucks and getting a few bills paid off first. im very close. I actually have a svt contour. but i love the cobra in fact it was between an 04 cobra and the 370z but i got a steal on the 370 so i could not pass it up. 358 miles 23 grand private owner. this 75 year old crazy guy. now thats a steal.

It is not a stretch, we did it on garbage California 91 octane in the summer!

You all know me by now, I always post and advertise conservative real world numbers.

Thanks, Tony

You stole it and honestly, the 370 is a better car (overall). The Cobra is dated now and aside of brute power, the Z is far more superior in every category. That is my honest opinion and I own 2 mustangs.

I am pleased to hear that you will be ready soon and I look forward to your phone call...

Thank you, Tony

Anyone running berk hfc with 18" FI cbe? Just ordered mine from Tony and he said it sounds great although fitment isn't 100%. I'm sure fitment issues can be corrected but how about the sound? rasp?

It was great talking with you the other day. Thank you for your order, we appreciate your busines...

Tony
