I'm looking at getting a hi-power catless downpipe and a hi-power catback, how loud is it? I looked it up on youtube and found a few, sounds quiet but is that just because of the quality?

I'm putting it on my 04 wrx, going to do an open source tune

BKBLITZED had catless DP and HKS Carbon TI and he got a ticket for volume(lucky it wasnt ref!) I don't know how the hipower compares, I am pretty sure its the same just without carbon fiber...

I heard the hi power is the same without the carbon muffler. People say its loud but imo its not that loud but that may be me

well ****... I'm getting them as a package deal so would I be better off swapping out the downpipe to get it quieter? or get a silencer?

It isn't THAT loud. MY APS 3 inch that looks stock is way louder than either of my HKS's.

I also have a HKS catback for sale if you want, 250 dollars.

If you had just the hks catback with stock downpipe, the catback passes (but sometimes barely) the 95dB limit (anywhere from 92-95). With an aftermarket dp it will be louder.

I used to have the hks carbon-ti exhaust with a catless downpipe. I didn't think it was loud at all. It wasn't nearly as loud as my helix exhaust.

Hell even my Borla XR-1 was louder than either of my HKS's

Really the xr1? I thought the carbon ti was like the nur spec r

The carbon TI is actually quieter than the hi power IMHO

Had that setup, cop said he heard me before he seen me. Let me off with a warning. Bought a maddad whisper to replace it.

And I bought it off Derek above me! Haven't had any personal problems with the exhaust I would say it really isn't that loud. A little too big and too angled but definitely not that loud.

Lol Ouji, I do have to admit when I got pulled over, I was flat on it doing redline shifts. If you drive with this exhaust normal, you won't have any problems, but what fun would that be?

i got pulled over going the speed limit. I was at around 2500 rpm so i guess it was had quite a bit bass and rumble
