Swflis350 Posted April 22, 2021 Share Posted April 22, 2021 Hey y’all! Brand new here and just got a 2006 is350. Car is in excellent condition but the cat is obviously going out. Throwing a p430 code and is obnoxiously stinky on acceleration and also has some black smoke coming out. I am decently mechanically inclined and obviously don’t want to leave it but don’t want to put an oem one on as its 250$ and aftermarket is not much more. I found this mid pipe for sale (I’m attaching the link) and I was wondering if it would delete the cat and fix the issue? Thanks so much guys. https://www.jmautosports.com/product/invidia-06-is250-is350-non-awd-mid-pipe/Default.aspx?gfid=p15473-c89350&source=googleshopping&utm_source=google&utm_medium=cpc&adpos=&scid=scplpp15473-c89350&sc_intid=p15473-c89350&gclid=EAIaIQobChMIkOfNuMSS8AIVDvnICh1hXgrvEAQYASABEgIb0fD_BwE 1 Quote Link to comment Share on other sites More sharing options...
dcfish Posted April 23, 2021 Share Posted April 23, 2021 Lexus does not make catalytic converters, Find out which Mfg. makes them for the IS350. I know Davico makes the cats for the LS460 😉 Quote Link to comment Share on other sites More sharing options...
Bykfixer Posted April 23, 2021 Share Posted April 23, 2021 It's best not to delete it. Especially if you live at a place with annual emissions checks as part of your annual safety inspection because it won't pass without one. Plus these engines are built with a known certain amount of back pressure in the outgoing system so if you upset that balance without tuning the computer that pretty much runs the car the results would be a confused computer. Who knows what squirrley stuff would happen after that? Try cleaning it. Quote Link to comment Share on other sites More sharing options...
