Nothing says you have to go long tubes.</P>


Cut-outs will out perform a pro chamber &amp; mufflers bolted behind it.</P>


If you plan on changing your throttle body, it won't give you much for performance because you still have your stock manifolds on the motor. In order to intake more air &amp; see performance gains, you need to be able to push that spent exhaust out of the motor faster. <IMG src=smileys/smiley2.gif border="0"></P>


4.10's are very streetable, they will only be 200-300rpms higher than 3.73's in 5th gear. </P>

If you Change the upper intake to either a Trick Flow or a C&amp;L. That would make more of a difference with the TB. But the TB deffently helps for the performance.

4:10s are the way togo. At 65 your only around 200 rpms faster then the 3:73s. I hade both the 3:73 and the 4:10. And i would go with the 4:10s any day.</P>
