    i would think a set of OT pipes on the logs would give you much more HP...also...zoomies over headers, being as its blown...the only problem i see is the noise factor in Cali!!!!...Havasu & the river prob wouldnt be a problem if your cool ...just sayin' my .02 cents

    on the dyno I saw a 40 hp difference between thru transome headers and over the transome headers. The over transome were bassett blower headers.

    I went from tt injected bassetts earlier this year...to ot injected bassetts. I noticed zero performance difference. Not that I expected to. I am curious to see what if any difference running them completly dry at wot makes.

    you might get 100-200rpm, it will sound meaner, and it will blue them
    headers quicker than you can believe
