SSIs vs. Headers, difference? Options

[DanT]

I currently have a stock 2.0L with SSIs and Bursch with Turbo muffler.
With the engine in stock trim will I find any noticeable power differences with Kerry Hunter headers or similar.
Is a bone stock 2.0L going to see any appreciable increases in power by changing exhaust.
If I do go to headers, will changing to a less restrictive aircleaner help power.
I thought I had read somewhere that headers on a stock engine actually reduce power at certain rpms.

All right have at it. (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)

Grassroots did a comparison a few years back on a 2.0,

in order of performance :

stock,
Kerry hunter header
Tangerine Racing Header

Personally, I'd go with a Tangerine Header* if it fits in your budget (I asked my wife this morning if I could buy one and she laughed at me...I wore my Tangerine Racing T-shirt today, damn did I look good, hahaha) (IMG:http://www.914world.com/bbs2/html/emoticons/rolleyes.gif)

Next would be a European Racing header** with turbo/street muffler...this is what I am running right now as well as a few other local /4 guys.

*about a $1000
**about $500 if ceramic coated (recommended)

You lose heat, but you also lose something like 20 pounds or so compared to a stock system.

Only way I see losing power with headers is if you went way too small (not going to happen with current headers out there and your motor) or going way too big, which only Tangerine offers larger diameter headers and I'm sure Chris would recommend his normal setup.
