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)

Hi Mike: were the stainless steel aftermarket heat exchangers tested with the others? roughly what was the change in power and torque in the tests? and which engine was the test made on? I want to get an idea of the gain for cost.

Hey Dave,

I cannot remember if the SSI's were tested or not, I "want" to say yes 'cause I thought they mentioned the SSI's being lighter than the stock steel H/E's. The H/E's were tested with a stock 2.0 muffler.

Motor was pretty much a stock 2.0, maybe a different cam, but nothing too radical since it still had the D-Jet.

don't qoute me (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)
~5hp gain for KH header
~8-9HP gain with Tangerine

according to the article and Chris, his would have seen better numbers on a more modifed engine

as to cost effective, I think it's relative to what your goals are...for most people just driving on the street, laying down $500 for 5hp might not be very cost effective
