Installed an hks hi-power SS and started to hear a funky sound and here is what it was.....three shots below....







The stupid resonator is hitting the driveshaft wtf!!! And yes it was installed correctly, went over it several times with my mechanic friend while on the lift...

 

that sux

 

Wondering if I should call hks on this one?

 

i would see what they say

 

Anyone heard of this before?

 

Happened to me when I hit some bumps... Just get the resonator taken out

 

That's why HKS exhausts are nothing more than shiny toys. You couldn't pay me to put an HKS exhaust on my car. I did extensive research when buying my exhaust and the very first company I ruled out was HKS. Funny think is that they make good products but their exhausts just plain suck. I wonder if someone else makes their exhaust and they just slap the HKS name on it....

 

Before calling HKS, I would try loosening the bolts, adjusting the pipes and then tightening everything back up again. This is a common issue if you search the HKS Hi Power/Carbon Ti on here. I've had it happen to me on both my HKS Carbon Ti and on my HKS Spec R and with a little patience and possibly another person to hold the exhaust steady while you tighten it you can get it all to clear.

FYI most of the cases I've seen, this problem occurs when the exhaust is assembled on the floor and placed on the car versus putting it on piece by piece. You could do a lot worse in terms of picking an exhaust. The HKS unit is a good piece that is not too loud. Sure there are others than make more power but I'd sacrifice some power for a bit more quiet.

 

HKS makes their own exhausts... I've been to the factory and watched an old woman stuff the muffler can with dampening material with a wooden broom handle, then the robot weld the can shut.

 

sorry to see

 

wow that really sucks. Hope you get it fixed.

 

My roommate has the HKS Hiper, and it's doing the same thing on his car. Of the four Evos at our house, only his car is doing that. Two of us have Apex Noirs, and the third as a RSR Exmag, no problems whatsoever. It's a design flaw on HKS' part.

 

mine fits perfect on my evo 8.

 

bummer. I was really considering buing an HKS. I guess I'll keep looking. Let us know if you are able to adjust it and make it work.

 

yeah i had the same problem and like it was stated just take it off and carefully mount it... it'll go away... mine was so bad it put a dent in the damn thing lol...
