What kind of gain in hp and torque can I expect from a 4 into 1 header on a 97 Tibby FX <img src=/images/forums/snitz/uhh.gif width=15 height=15 border=0> I have aftermarket 2 1/2 inch exhaust and racing muffler
The only way to know for sure is to dyno the whole system. With the 4-1 configuration you will find most of your power gains in the higher rpm range. ie. 4500 and up. The 4-2-1 config will give you power a little bit earlier.
Anyone have the dyno results?
