so i love the exhaust, but it is RASPY as all get out between like 3200-3900 rpms...sounds like a group of *(sp?)* zachadea bugs hissing...
i've read this is because of the flex pipes they use and the ones of us that run test pipes?
so first, is that true?
second, what can i do to get rid of that noise *(aside from getting a different exhaust)*

i was thinking i could have pipes made to eliminate the "x" and the flex pipes.
have them running individually from the test pipes to the muffler section, no "x" or "H" pipe...

can or will that work you thinks? thanks!

 

the x pipe is there to help reduce drone/rasp. Maybe you should get the motordyne art pipes to help reduce rasp?

 

this exhaust sounds terrible with test pipes. Thats the main reason i would never purchase it.

 

It sounds pretty good in the clips with Berk HFC's but I have never heard one up close in person

 

This is common with all exhaust system for the VQ platform. Put a testpipe and HFC on you will get this rasp.

 

Cool another rasp thread. I hope we can get to the bottom of this.

 

The ARK Grip exhaust just like the HKS, you change from the stock cats and it gets raspy. Get motordyne TDX :P

 

Replace the resonators with longer ones or x pipe muffler

 

HKS has a Hpipe and ours have a X Pipe. The thickness of the steel is different as well.

 

This exhaust would be great for say idk......600$. However for the price their selling it 4 and comments iv heard after HFC or TP install would def make me stay away from it. Sell it and get something thats not copied ex MD

 

+1 on the md. Or get art pipes if ur not too thrilled about 1k + on an exhaust. But honestly anything motordyne makes is awesome.

 

Only if it was copied.

 

i didnt have any rasp on my AP setup and i deff dont have any on my new MD setup. i do have art pipes though...

 

hows it NOT copied? r u sure you want to argue this with me?

 

 

because of their X pipe? I don't know, this argument is in every ARK dual posting....

 

i know its gets old. Why stand up for your company if its built off replicas?

 

so would running straight custom pipes from the tp to the exhaust not get rid of that?
i mean take out the x pipe all together and just have basiclly two single exhausts? i know that the 370z my buddy has is set up like that...thanks!

 

I don't run their exhaust but i have seen it. It may be a replica ( HKS and ARK are both dual exhausts ) but they finished where HKS left off. ARK's redesign eliminates what others had to do to their crappy GayDM exhaust to make it sound good. With a proper flowing X pipe they probably even make better power then the GayDm exhaust they modeled theirs after.

 

i have actually heard this exhaust as well. Of course with stock cats but yes it didnt sound bad. My frustration is they always post and say its not a replica. Im sorry but if they added and subtracted whatever and that makes it its own design no a knockoff then every wheel rep is also not a knockoff. SInce they offer diff colors/specs/sizes. Get what im saying?
