So I just put an hks hi power exhaust on my car and I'm happy with throstle response and the deep tone it has. Although I want more deep. I have looked into test pipes such as berk but want to avoid the bumper cleaning, smell and engine lights. Do hfc change note at all? I'm up for all ideas!

 

Why does everyone like starting threads in the wrong section, especially this one????????????????????????????

 

I'm going to start issuing infractions w/o a warning if this keeps up.

Thread moved to the exhaust section.

 

Sorry first thread post, trying to figure out how this forum thing works. Apologies

 

There are several options, test pipes are definitely an option they generally will increase noise and also power but could lead to some rasp, HFC as far as I know don't effect sound very much but maybe a little increase, and you could also look into adding an x pipe it will quiet the exhaust down but also make it a little deeper. Definitely youtube these options and see what you like.
