i know the 2.75" exhaust will make more power for sure, but if i use a smaller exhaust like a 2.25" will i create more power in the low end, coz i find that highend have more then enough power, but the low end needs some more power.

btw, i have CTSC w/ AC

so want to know if it'll make a big difference if i use 2.25 for the low end, or basically the same even i use 2.75" or biggest exhaust. what do you guys think?

 

my exhaust goes 3in splits to 2.5 opens to 2.75. produce loads more torque, got around 160ftlbs at 4000rpms, so where you put the smaller exhaust matters so you dont end up with too much backpressure

 

that's one of the problems with centrifugal superchargers. they make boost as your revs increase. so you end up making plenty of power up top, but the low end stays pretty skimpy. i wouldn't start messing with the exhaust to try to get some more torque, the difference would be minimal, and you would end up choking the top end.

 

Add 4.57's to get into boost faster. No added torque, but may feel like because you are going through the rpm band quickly.

 

gears + sc = the winning combo. i'd go with 4.57's or 4.77's.. anything lower isnt really worth it over stock.

 

Smaller pulley + supercharger = more torque and more top end FTW.
