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)

So with euro pistons and head work the headers mabe a difference over the stainless steel exchangers per the comments on this post. I guess that still leave the original question open, what advantage to a stock 2 liter engine (ie USA version pistons, stock heads, no porting0 My assumption would be that the the headers would have less positive effect in this case than the other.

i would rarely rev my 914 past 5000 rpm, so i wonder the extent of improvement at the lower rpms if any with the modified engine, and also with the stock engine with headers attached.

still don't recall what year model we are talking about, the last 2 liters (75/76) had some differences that gave them less power than the early ones.

what will be your application and driving style? What ads power to a prep'd engine that runs at the higher rpm scale may not help much at all on a bone stock engine driven at more conservative rpms. Again, i suggest you ask HPH for advice, as they do everthing from stock little ole lady drivers, to full all out race 914's. tell them what you got, how you want to drive it, and then get prices and see if that is what you want.

good luck on your choice, let us know what you decide
