installed my TRD exhaust on 04/10/04. it sounds so smooth. it is not loud! my intake sounds just as loud...hehe!
Compare the old and new TRD exhaust.

The old one is just a lil "rusted" that is from one year of NJ weather.

After installation. The hanger took a little long but no big deal. The job took less than 45 minutes.

installed ground wire set. I brought a set of ground wire off ebay and see if it works and it does make my car more stable at idle. in term of HP, well, not much at all. i still think is a good product. i will get a better set of wire later in the year. The "sun hyper ground system".
also installed the NGK IX iridium spark plugs. when I pull the old plugs out i found out that it is NGK also but in the manufacture booklet it claims to have denso iridium plugs??? anyway, it feels good. it feels like it gain a lil power from the plugs and the ground wire set. give it a try and you know what i mean.

installed the Sun hyper voltage system. it is great! don't feel much HP gain but it helps my gas mileage!
usual winter mileage is 28-30 max and now i get 30-33 max. 10-15% gain in gas mileage which save me gas money in the long run!!!
