cool thanks bro, im also talking to wayne of ppi hes a super nice guy.

 

why would your car be down for an exchange? They send you a ported one and then you send them yours back when you install the ported one

 

yeah i know thats how the exhange works. if you dont do the exhange i can take mine off, send it, and he can port mine and send it back. either way.

 

I'll vouch for APEX, they do great work.
