From the description of the product, not sure if it's catback but it very may well be. Has anyone tried the HKS exhaust system? Any thoughts such as power gains & sound level? Here's the link: http://www.eautoworks.com/html/home-...=Desc&sort=key

Thanks in advance guys.

 

I have the HKS on my car and i tell you that it's very nice deep sound, but not ricey and annoying. It does seem to make the engine a bit torquier, but nothing that'll guarantee you a race over dead stock, and my miles per gallon actually went up by maybe 1 mpg (when i'm not flooring it; i tend to a lot to hear the nice sound).
It's not a full catback, it connects after your B pipe. You'd love it.
Here's a picture of it...

 

my hks just came in the mail... i noticed that one of the tips was longer than the other one...is this normal?

 

yes the bumper isnt exactly flat... so thwe tips follow the line of the bumper in a way.

will

 

The one tip being longer than the other shows HKS' attention to detail. The tips fit the contour of the bumper perfectly. Glad I got the HKS when I got the car. Makes the car sound a bit more aggresive too.
