HKS Hi-Power Exhaust question

[bam2k4]

Noob here, just purchased a 2005 mazda 3s 2.3 and was wondering how much horsepower can I expect to get from a HKS Hi-Power Exhaust? Is it really worth 500+ dollars and how loud will it be?








oops, please move to proper section

In regards to the HP gain...you will get very very little. It will only feel like a lot due to the sound. As far as how loud it will be I dont have any clue.

$500 is a good deal for an exhaust...exhausts are expensive.
