I've read numerous posts that state that a super free flowing exhaust w/ very little backpressure will actually move the low end torque up the power band. Is this true? I am trying to decide what I want to do w/ my stock exhaust setup. But, I am also very attached to my low end torque (the one thing, I understand, that separates us from the LS1 crowd). How far can I go without losing my low end torque? Thanks, guys.

 

Pick your powerband and the question will be easier to answer. Keep in mind that you might only want to build one exhaust as they get a bit expensive...

a) 2500-6000 rpm
b) 3000-6500 rpm
c) 3500-7000 rpm

(A).... definitely.

 

Long tubes and catback will serve you well

 

2500-6000....

Yeah, long tubes will pick up low-mid range torque and the smaller 3" cat-back system isn't gona cost you anything power-wise.

Just keep in mind that increasing engine performance (unless you stroke the engine) means raising the rev-range. That said, I think people worry a bit too much about what happens outside that rev-range they're building for. No free lunch.

I agree,this is about the best set up unless you are getting real serious.
