well if the exhuast u built is over 2" you are loosin low end power
make a cold air intake
get a performance header

 

the ehaust is 2 1/4 inch, and yes the low end is the worst for power. thanks for the help

 

adjust the timing to no more that 15deg.. BTDC

Am I leaving anything else out guys? I'd reccommend not sticking with the 2.25" exhaust. 1.5" should be plenty, and will help your bottom end out.
