I have installed the comptech headers and the new springs to lower my car down 2 inches and got the new shocks. What is the best upgrade I can do to my Cl Type-S to improve the performance for a price under $1000

 

comptech exhaust and a cold air intake--probably get both installed for around $1000 total. Or you can buy my 75-shot of nitrous system for $500!

 

An intake is a must for performance. But the exhaust is 99% just for looks and sound, not too much performance value.

 

Get UR Pullies and CAI (Injen or AEM) and you are all set. If you want a "cheater mod" get Nitous Oxide.
