noone makes a throttle body spacer and if you are getting a new header and exhaust, i wouldnt suggest getting a high flow cat because you do need some back pressure but if you muth, they sell them at modernperformance.com

 

Replacing the stock header with a short tube header is a waste of money...especially replacing it with a lower quality Pacesetter...the gains will be minimal at best.

 

all depends on what your looking for... Before the turbo, i changed from the stock exhaust manifold to the magnum manifold. He is right the performance change was minimal. But the weight savings is large, i would say at least a 5lb difference.

remember with weight redux... its not one place to take 100lbs, its 100 places to take 1lb.
