hey i just got a $15,000 reenlistment bouns for staying in the army another 2 more years and was wondering what part you think i should buy for the mazda. Im interested in both the cp-e maf ci and the magnaflow exhaust. Im aware that the magnaflow adds no hp really but would make the car sound great. The wife is only going to let me tint the windows and one parts because we have debt to pay off so please help me out in deciding!!! Thanks i appreciate it alot. Btw i have the 2006 Mazda 6 s mtx.
