Well I have decided to upgrade my exhaust on my 86 n/a 5 speed and I was just wondering if one of you z gods out there would give me a little advice? I have been searching some sites and found a few set ups and was wondering what was the best? Should I even get a set up off line and have some one install it or should I just go to a local shop and have them make me something? No matter what a shop is going to do the install. Should I do my headers to? How much should I expect this to cost? How much hp should I get? My main concern is the sound, I do not want my z to sound like it farting every where I go (man I hate that rice crap). I am not a mechanic by any means so all of your input is greatly appreciated.
