I would love to get some help finding a few aftermarket performance parts for my ES. I've been trying to find a set of upgraded injectors, the only performance ones I have found were far too big(650cc) for what I need. A little bigger than stock would be great. Also I would like to find a nice bolt on cat-back system.. I've built a few of my own, and have good luck with sound, but I would finally like something a little nicer! And any info on aftermarket intakes would be appreciated, the only one I can find is a Weapon R, which I'm sure would work fine, it's just really hard to look at without laughing!

 

Best bet is to have a custom y-pipe made by an exhaust shop. The stock pipe is poorly designed and restricts flow, if you combine it with the AFM tuning and ignition timing advance you'll get a nicer running engine and gains at higher rpm. The rest of the exhaust system doesn't need anything done to it you won't gain anything by larger pipes or different muffler besides noise.
