Anyone have an HKS Hiper Exhaust w/ the carbon fiber muffler and titanium tip? I can't decide between the Apex N1 single or the HKS. I've seen some pretty impressive results with the Apex unit, but I've never seen anything about the HKS. Thanks.

Id say get the Apex N1.I have heard good things about that exhaust also its pretty damn popular it seems.Im getting the Apex N1 for sure when I buy my FD.I dont know anything about the HKS exhausts but its something to look into.If I come across some info on the HKS i'll post it.Later

I've got an Apexi N1. There's no dobut it flows but it's so damn loud. I got a silencer but that cuts the hp noticably.

I've got an HKS Super Dragger II and I love it. Quiet at idle, nice and throaty at WOT. The only thing I dont care for is its size.

What gives the most hp though?Thats all that matters to me also I like it loud.

I had heard that the HKS Super Dragger I (not II) was almost worse than stock. I personally thought that was due to a number of other things involving the exact car it was on. The Dragger II was in fact a significant improvement, vouched by many (search, I know its there) Thats about all I could tell you... no HP #'s though. Sorry

Regular Hiper(not Ti or Carbon) and Apexi GT are the best. Apexi GT has 80mm piping.

I have the HKS Carbon Ti and I think it's a great exhaust. The piping is pretty straight with minimal bends and the canister is large enough with a big ti tip at the end. Not sure how it compares to the other in terms of power but this one sure gave me a nice smile.

Kinda quiet at idle and very deep once I get on it, especially in the 3k-4k rpms.... And from what I hear the N1 is quite a loud *****


Here are some quick pics:

I say apex N1 thats what I have and it's pretty good. Yeah it's loud but it sounds pretty good on a RX7.

the HKS hiper racing is the higest flowing, it has 4 inch piping and is from the dp back. the muffler in titanium but the piping is ss. the GT spec is the highest flowing Apexi makes. from what i hear it has 3.5 inch piping and only the cansiter is ss.

Are you sure the entire canister is titanium? I thought it was just all SS. The HKS Carbon Ti is exactly the same as the Hiper except for the SS canister w/cf wrap and the titanium tip.

apexi is higher pitch, Hi-Power is way deeper and much more beefier sounding. this is on an SR20DET, but should be the same scale on your cars as well. piping bends looked similar, but apexi seemed to be a little straighter

I guess I'll just have to do a bit more research. Thanks for the help though, and thanks for the pics EvilPeNevil. I'll post my decision and install pics when I finish.

Whats the differences between the Apex GT Spec and the Apex N1.Which gives more hp?What's the better exhaust?

Scrapiron7

The GT Spec has bigger piping but it's loud as hell. With my silencer out I really have to pay attention for cops in the area.

Hey evil, thanks for the pix. I'm thinking about that CarbonTi. I've heard it weighs very little. do you know the weight?

That's one reason why I'd like to get the carbonTi. Also I'ts got to at least be a bit quiter than my current Greddy Power Extreme.

3RotorRocket

So the bigger the pipeing the more airflow which equals more hp right?

Actually I don't remember how much it weighs, but it's not very heavy. I had it on the scale right before installation but can't remember the figures, but it's at least twice as light as the stock catback tho.

Generally speaking, that is true. I was aware the GT-Spec would be loud but I wanted the best flow.

Yeah it's pretty noticable. I did have the yokos all around until the front ones were so worn down that I bought some used SX MXX3s so that it'll were out more evenly with the rears, which are getting there.

The Apex GT spec exhaust with a resonated(oval muffler in the middle) midpipe is fairly loud, but tolerable enough, one cop pulled me over but it was just to ask me about my car.
