How many of you guys are running the HKS HI-Power catback? And do you like it? Also how much hp are you guys running with it at the wheels? Thanks

 

I would do a search bro theres been alot talked about this topic =)

 

I have the HKS Hi-Power, I love it. I don't know how much power it added just by itself (i installed it with the test pipe and downpipe at the same time). But the tone is nice and the power gain is nice too.

 

my brother and a buddy of mine have the Hi-Power, they really like it. It sounds mean as hell at idle(cams of course), and at WOT its pretty f***ing sick. I have the JIC and it's got a way deeper tone to it(i love it and it's 3.25").

Don't really know power gains though. when we installed the exhaust on our cars, we did several other things too.

 

I have the HKS Carbon-Ti Catback(Pretty much the same exhaust). Last time I got it dynoed I put down 290whp. I would guess I am at 320-330whp after the new cams and reflash. HKS is a great product and fits like a glove. I have always used their products.

 

290 WHP WITH EXHAUST ALONE

 

I also am running the Hi-power, but the 30th Anniversary one, cant say anything bad at all about it.

 

No, that is with other mods also. You don't pick up much at all until you tune the car to the mods.

 

I have the Hi Po exhaust and HKS dp and think they're both great. It has a nice deep rumble, but not too loud and the fit is perfect. Most of the US companies should learn from HKS about fitment.

With the exhaust, Power FC, MBC and a K&N filter, I put down 260 hp on a Mustang dyno and ran a 12.5 at 110.

 

I run the HKS hi-power 30th and i am making over 300whp. soon on race gas i hope to be over 350whp.

 

Is the HKS Hi-Power 3"? I heard it was like 2.978 something like that.

 

It's 75mm. 75 / 25.4 = 2.953"

 

Its not even 3" . Does that make a difference at all thats not 3"? I hope not

 

It's 1mm off from being 3". It's not going to make a difference you're going to notice. The neck-down at the cat will be bigger restriction.

 

Don't know if it's 3" or not but I make 612whp with it.
