ok two questions, are the mac long tube headers any good? cuz ive heard the JBA shorty ones dont put out that much and my friend has the mac long tube ones and he says their good but i dunno....also does a new pulley make much diff. and if it does which one would be better?



Mods:
MMR high flow intake
custom H-pipe with dual flowmasters
235/40/18 tires
limo tint

 

The alt pulley frees up 4-5 hp, I have the mac shortys and they were a bitch to install. don't know about the long tubes. Depending on your mods you have to decide if the 3-4 hp is worth it. I think it is.
