The cheapest place to get the CTA is also the most expensive place: from
CTA motorsports .
I don't know which exhaust parts are good, I haven't done my exhaust yet.
I found that the CTA makes my mileage worse because it just makes my foot itch to be pushed down more. When I took it out, I would push the gas, be disappointed, and give up on trying to go fast... mileage improved.
I suspect that intake, exhaust, and chip pretty much covers the main affordable and effective mods. But seriously, the timing belt ought to come first. While you're at it do the water pump and change those little idler pulleys.
