ok heres what i got... well will have... im gettin a vortech charger that puts out 8psi and im gettin gears... ahvent decide on 3.73 or 4.10... but thats off subject i want to kno what exhuast will give me the most horsepower... sounds isnt that big a deal.... if there all goin to give the same hp then im show around on how they sound but whats the best setup from headers all the way bak preformace wise not sound quality wise

free flowing with no cats will give u the most power

honestly u get almost zero gains from the exhaust

pick it because u like the sound of it

btw since u got a supercharger i'd go with 3.73's.. 4.10's will cause u to shift too much

any free flowing exhaust like above mentioned and get 4.10's you will not be dissappointed

drhoward

didn't they get something like 20 hp from a full exhaust on horse power tv? I wouldn't say you get no gains

chambered mufflers like flowmasters produce less hp than straight throughs like a magnaflow with a huffer

You get the most gain by getting rid of the old one, and then you lose gain by putting on an exhaust. So that is what is meant you don't get gain with exhaust.

You will gain HP from exhaust but it will be minimal. You would be able to tell though with a full exhaust.

Also, I definetly would NOT get 4.10's with a blower. 3.73's are ideal... maybe even 3.55's.

Get exhaust for sound, not power.
