Looking for best/cheapest cold air intake? Anyone try the spectra or aem?

looking to make the 2.7l run and sound better, was thinking spectra or aem cold air intake and maybe getting a flow master super 44 muffler welded up? And was wondering if you guys used any sites to find cheaper or used parts for Toyota tacomas I'm located in WV

 

youre wasting your money if you think a cold air intake is going to make a noticeable difference in performance. it will effect sound tho. i would get something with aluminum tubing to resonates and makes a better tone than plastic. save up your money and get a proper exhaust too. IMOP flow master makes our truck sound like annoying cars. like a V6 accord with a fartcan mounted on it
