Sorry no pickups will be coming from another warehouse in WA.

 

will the Evolution not fit any other 4th gens?

 

its not recommended.

 

what is the difference?

 

Evo is for the new maxima models 99+
I have the SP on a 98 maxima very nice (not loud) actually sounds very good.

 

the SP is not a 3" is it?

 

will the evolution be ok on a 2003 GLE?

 

Yep.

 

what is the difference between these two?? i have a 99 which one is better??

 

Evo is better for your car.

 

What is the difference between the SP vs. EVO models? For normally aspirated (non-turbo) cars there is no major difference in our GReddy SP and EVO systems. Except the styling in the out side appearance (and most EVO systems have the piping diameter stepped up a size right by the muffler section). Generally the systems sound identical to each other. On non-turbo cars, with the exception of the EVOs being 1-1.5dba s louder (undetectable by the human ear) the internal construction of both systems are almost identical. All GReddy systems use our unique straight though design. However for turbo cars, there can be a big difference in piping diameters and pipe routing. Although again the internal construction is the virtually the same the turbo Evo systems are designed to try to maximize flow.
