I had been waiting for 7 weeks for my HKS Hi-Power Exhaust and it finally got here yesterday. I had Altered Atmosphere install it along with their A.A.M Spec test pipes. install took just about an hour. This combination together is absolutely loud. i love the sound of this exhaust. and yes i know this tread is worthless without pics and vids! LOL i'm working on having Dave from Altered host the before and after pics and vids he took. should be up soon.

Thanks,
Jay

 

Is there rasp? Can you describe it?

I'm thinking about going with test pipes as well.

 

it is extemely deep up until 4,000 then it gets alittle raspy. not at all nice a civic or anything but the power above 4,000 is absolutely amazing. Dave from altered has all the vids and pics before and after. tring to have him host them up here.

Hope this helps,
Jay
