loss of torque?

i recently installed my tsudo exhaust and it feels like i lost some torque

could this be due to the fact that the exhaust is 2.5"?

or could it just be that my powerband has shifted to higher RPMs?

if i really have lost some torque, what are some mods that i could do to regain torque because i simply just love the tsudo exhaust

what i am thinking down the road is long tube header and a tune

along with 2.4 intake mani and throttle body which i know will make it worse but im hoping the tune will make it benificial

those are not on the car at the moment

it could just be that the powerband shifted, cuz when i shifted into "I" today and floored it, it felt faster

It probably is faster, and you probably have lost some low end torque, below 2,500 Rpm. But, you should have shifted the torque curve up maybe 300 Rpm, so I believe that the car would feel faster, when flooring it, it never goes below 3,500 Rpm anyway.

And, you sig is tooooo big.

Yes you lost a lot of low end torque but gained some up top, that exhaust is pretty big for a 2.2 auto with little mods.

because whether there are two of them or not, its still pronounced the same. If you look at a a pacesetter header it has the word "Headers" stamped on it clearly...

Because the term "header" refers to the head pipe, of which, you have 4 (plural)... So unless your installing a head pipe on a single cylinder 4 stroke engine, its headers.

Or "header" could just refer to the entire exhaust manifold. Either way really.

Actually Pacestter call them headers because they make lots of them, "headers" is plural for "header" We only have ONE so its a header, LS1s have two, so they have headers.

Head pipe refers to head pipe, header refers to a bunch of head pipes welded together.

Ever wonder why if the entire unit, regardless of how many a vehicle used, were called "headers" than why do they use "header gaskets" and " header bolts"? Its because the unit isnt called a "headers". duh.

I could agree with either. I personally use 'header', but Ive always thought of them as head pipes with a collector. Of course, they all do share a common flange, so... hmmm...
