Video Request - Ark Grip Exhaust, Ark Test Pipe, and UEL Header - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Acree · 03-02-2014, 03:35 PM

I've looked high and low all over youtube, google, and the forums for a video like this, so please forgive me if it's something is easily found. I am looking for a video showing the exhaust sound with the following components:

Ark Grip Exhaust
Ark Catless Front Pipe (resonated test pipe)
Any brand of UEL header
Stock or aftermarket over pipe - don't care

I have a JDL UEL catless header on order and already have the Ark Front Pipe and Ark Grip exhaust installed. I'm concerned that this setup is going to have monumental amounts of rasp even with the 3 helmholtz resonators installed. The system doesn't have actual perforated pass-through resonators anywhere, which is what I believe cuts down on rasp the most aside from actual cats.

If you're an owner with this setup, please chime in and share your experience or opinions.

I am about to pull the trigger on a somewhat similar setup:
JDL UEL Header
Nameless 2.5" Catted Downpipe with Helmholtz Resonators
Ark DT-S or Grip Cat Back Exhaust

The only thing that is stopping is that I am having second thoughts about the CBE. I can't find anything online or anyone that has this same setup that can convince me that this won't give me any rasp/drone issue.

Well I now have this combination on my car with a JDL UEL header.

Pros: As far as I'm concerned, this combo hits the holy grail of exhaust systems. It's quite when you want it to be, and loud when you want it to be. If I roll the windows up and turn the stereo off, the tire noise drowns out the exhaust. It is literally that quite. If you dig your foot into the pedal, it growls and lets you know it's still there. If you roll the windows down and give it the beans, it screams from 2k all the way up to redline. It really is a fantastic sound.

Cons: THE RASP! KILL IT WITH FIRE!! This is the only down side to this combo as it currently sits. The sound has a rasp undertone anytime the car is under heavy load (>50% throttle). I expected this considering the car has no cats and every single resonator on the car is not an inline resonator chamber, but a helmholtz resonator. The ARK resonators do a fantastic job at eliminating drone. There is literally ZERO drone. I cannot overstate this enough. THERE IS NO DRONE. If you set the cruise control with the windows up and the stereo off, it's quieter than stock. But as soon as you load the car down, the rasp comes out.

So, to fix this, I'm going to buy an inline same diameter resonator and have it welded into a section of the test pipe. I did the same thing to my 350Z and it worked wonders. I believe this is a necessary fix for this combination. Rasp is unacceptable on any car, especially with a nice exhaust system like this.

sound clips or never happened.

In for sound clips as well. I planned on eventually getting a header. (Have JDL op, ark fp, ark grip cb)

hakkoo · 04-11-2014, 01:46 PM

+1 for Sound Clip!
I have JDL UEL sitting in my garage will probably go on next week (needs warranty work done at dealer before i can put it on) i have a Motive OP, Motive HFC Front pipe and ARK GRiP catback. always wanted to hear what it would sound like but got tired of waiting for one so i pulled the trigger on it.

I believe a catted front pipe will also get rid (or at least reduce) the rasp.
