Kerry hunter or stock SS exchangers for my '74? Options

[JonH]

Help me decide what to do with my '74 2.0l. I plan on removing the aftermarket dual tip muffler I have now to go to a stock set up and rear valence. I've got both a brand new NOS Kerry Hunter header and some nice used SS heat exchangers and exhaust along with a stock valence.

Question is this, will the headers make any difference on a stock FI 2.0l to warrant the expense in making a custom muffler work or should I sell the headers and stick with heat and the SS pipes? Other than maybe a digital ignition I don't plan on doing any mods to this engine which makes me think I won't see much gain with the headers. Anybody know if headers will even get me 5+hp out of a stock 2.0?
Thanks

Grassroots Motorsports magazine tested a Kerry Hunter/Supertrapp setup in February 2002. Their baseline peak HP was 106.9 at 5100 rpm produced from a modified 2.0 (9.2:1 CR, Web-Cam #73 cam, and Euro P/Cs), SS heat exchangers, and stock muffler.

The Kerry Hunter/Supertrapp produced 111.3 peak HP at 5100 rpm.

They commented that the Kerry Hunter system was "louder, but certainly not objectionable." Also noted that it's 16 pounds lighter than SS exchangers + Bursch exhaust.

These data aren't from a stock setup, but may be a good reference point for you. (IMG:style_emoticons/default/type.gif)
