AZis350

Yeah they talked to me beforehand and said I have a total of 4 cats 2 by the manifold and 2 midway, the 2 that they deleted are the midways.

GHL Motorsports and they replaced from the "axle back".

so the solution it to have the primary cats still intact, and the o2 senser does it have to stay or if removed more headaches?

I just had my exhaust installed a few days ago and havent had any issues until today. My Check engine light came on, So I went to Lexus and the ran a diagnostic on it and came back with a code error P0420 "Catalyst System Efficiency Below Threshold (Bank 1). They are telling me its because of the new exhaust. I have search on the forum and havent found much help. Does anyone know how to fix this? The cats were removed is this causing the problem? I have a 2006 IS350 Thanks for anyones help. Mike

I should have IS350 back from the shop tomorrow. My Exhaust is a Axel Back system and is all redone, when it is finished then I post pictures and a video. The shop that did the work is GHL Motorsports In Mesa, AZ. This is a Prototype system they are just starting for Lexus.

Thanks a bunch the Swell website is great. I still think I am just screwed unless I find a totaled IS-F in a junk yard to pull the other stuff out. (doubt that will happen).

I want to replace the wood trimming on my IS350 with the IS-F Silver Carbon Fiber. I went to a parts department to check it out and they are asking $1947.92 for just the center console. Not including the front and back side pieces. Where can I find this? I also have an Audi A4, I have found a number of sites that have OEM parts for a fraction of the Dealer prices. Does anyone have any ideas on what to do for a site similar to Lexus? I just got another quote and for the whole replacement of wood parts to the Silver would be about $3000 not installed. That seems very high and ridiculous. Thanks, Mike

I would say I drive 60/40 60hwy and 40city. I also just took a trip to Tucson and I got 28 on the Hwy that was going 80mph and not flooring it. This is just as good as my 07 Camry on the hwy. But the Camry has the IS350 beat in the city but by only 3mpg. Overall Very Happy, I have the power at my feet but still maintain my MPG's

Just bought my IS350 and ran through my first tank and go 22.5 MPG with me punching it a few times. not too bad IMO I just traded a 2007 Camry for this and I was getting 25 avg MPG

Hey Randy- I just bought a IS350 and would love to get something together for AZ. Let me know. Thanks, Mike
