I am in the army and deployed. When I get back to the world I am going to drop a bit of money into my 07 TSX. I am going to put in a CAI. Which one is the best out there with out Probs down the road? I already was going to go with the Injen CAI. I want to put in a performance exhaust head. What is the best out there too? Will I have to upgrade my whole exhaust system? I am also going to chip my car too. Whats the best out there?

 

Injen is great intake and would be a good fit for any TSX; as for exhaust header, there is several options from DC sports 2-pc, CT-E or Weapon R header-testpipe combo. Exhaust depends on your goals, price range and preference. As for a "chip", the TSX has no chips available, just Hondata reflashes for the 04-06 models. Since you have an 07 you are going to be out of luck. Hondata doesn't seem to care at all about the TSX platform anymore so be patient or find another car to mod. Stay strong brother and thank you for your service.
