Anyone having problem with HKS exhaust? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

bjun · 11-24-2013, 11:49 AM

Hey guys, I have a HKS HI-Power Spec-L Exhaust for the BRZ, and I installed it myself. It's been over 6 months, but I recently noticed a problem. I lowered my car, which sits about 3 inches off the ground. But, sometimes when I go over bumps I hear a loud bang. When I looked under my car yesterday for the first time, I saw that the midpipe of the exhaust is sitting 1.5 inches off the ground. Is it normal for the pipe to be angled downwards where it sits lower than the car itself?
Point 1 is 1.5 inches off the ground and point 2 is 2 inches off the ground.

I don't have any comments on the HKS exhaust but I'll just leave these photos here

So I guess it's normal to be like that
I feel like it's going to break some point in time though :/
So yours hits the ground often also?

welcome to having a lower car you just need to take it slow over bumps. you can try smaller hangers but it might pull you exhaust tips up to the rear diffuser too much

Well it's the way the exhaust routes I guess. My exhaust leaks at every flange (front pipe) (mid pipe and the rear) but you have to remember I'm lowered over 4"s and I drive on it

I'm putting my stock exhaust back

It's quite annoying. Especially because I paid a good amount of $ for the exhaust, and it's scraping everything...

How low is your car? I am going to be lowering mine in the future, and don't want to scrape my exhaust either.

If you're going to lower your car with intentions just to go lower slightly and not slam it you shouldn't have an issue as long as you take care going up stuff

my car is about 3 inches off the ground. Lowest the kw coils will let my car go without needing camber plates

photos of the the pipe routing was pretty freely available. my suggestion would be to trade it in for something that takes the stock exhaust route so it sits higher up under your car. i have the legamax and clearance is a bit better than the hi-power.

the nameless also hangs kinda low.
