x2000GS300x

i was considering headers for my 02 gs300, but decided against it because of emissions testing in my county. The header i was considering buying was from Mazzuri Super. Their website is http://www.mazzurisuper.com/ and run about $850. Out of the others I looked, these appeared to be constructed much better. They were also helpful over the phone and email. see ya. search some old posts..... i know obx has them, i haver heard to stay away from them butt jefftsai has them....u can ask him (pm me if u need contact info) http://www.projectgs.com/diy/Engine/HeadersGS3/index.htm carbon modified some is300 toyomoto ones to run on his gs http://us.lexusownersclub.com/forums/index...showtopic=43637 i think rmm used to make some but i dunno good luck whats all the wireing for?

Hi im new here and I dont know allot about my car so ill explain and hopefully you guys can help. Well I have a 2000 GS300 and I decided to change the sparkplugs my self so I took apart the throttle body and all sensors going to it, changed the plugs and put everything back togeather, (well I thought I did) I forgot to put the botom screw conecting the throttle body to the intake manifold and I started it up and the car would bog out and shut off on me so I started it again and accelerated it to keep it on but it would gon to about 5000rpm and drop to about 1000rpm repeatedly so I decided to shut it of then I realysed I forgot the last throttle body screw and I put it back and it started up and ideld perfect but now wen I hit the gas peddal it will only accelerate wen im at 90%+ throttle, I took the throttle body off and I noticed that the throttle barelly starts moving wen the throttle cable is almost 90% pulled and some lights came on that werent on before like VSC or something like that and something else along with the check engine light and wen I put it in to reverse or back to drive it feel really harsh. I have tried to fix it but I cant so Im asking enyone here that knows whats going on for help. Thanks in advance.
