  3. Anything wrong with dumping exhaust after catalytic converters???

    Performance Intake & Exhaust Systems
    Hello, I am just curious if there would be anything wrong with dumping the exhaust on my Tundra after the catlytic converters where it unbolts there on both sides before it reaches the muffler so it would be catalytic converters then a little bit of pipe and then dumped. I have a 2008 5.7L
  4. Magnaflow Aftermarket Catalytic Converters (2003 Tundra SR5 V8)

    1Gen-Tundra
    So I just got my 2003 Tundra SR5 V8 back from the dealer after my frame swap and he made me aware that my exhaust was really rotted out. In fact when they re-assembled it, a couple holes opened up in two of the pipes and now I have a rather nice sound rumble-y V8 (which won't pass inspection due...

    1Gen-Tundra
    I just got a 02 tundra with 3.4L v6 and the catalytic converter code p0420 going off. What is the best approach to fix problem? 1) replace catalytic converter 2) replace with some exhaust system (without making a ridiculous matchbox car sound) 3) don't worry about the light I do believe the cat...

    1Gen-Tundra
    Hi, I am new to the forum. I have a 2004 Tundra Double Cab with the 4.7 V8. A year ago, the trouble code for the front O2 sensors came on and these were replaced. More recently, I am getting a P0430, which is, as I understand it, the passenger side Catalytic Converter system efficiency. My...

    1Gen-Tundra
    Q1. I am trying to purchase a refurbished, OEM, drivers side Cat from "Smith Cat", a company out of Illinois. They offers these guaranteed OEM cats for about half the price of new, and they've got a pretty good warranty. When I gave them ALL of my info they said that there were several options...

    1Gen-Tundra
    I know this has been an epidemic kinda thing a few years ago, but I guess it's still happening. I remember around 2009, or so, how it made the main news and media reports....but never thought it would hit home personally :mad:. I'll go "search" in a few minutes, but wanted to VENT my ANGER...
  9. Gen 1 - Cat Converter Replacement

    1Gen-Tundra
    Hi All, So while debating the $1400 quote to replace the catalytic converters on my 01 Tundra V8, I'm leaning more towards doing them myself. I have ramps to raise the front so I can get to them, and I'm checking pricing on the parts. Had anyone here done these before? If so, any insight...
  10. P0420 code - How to diagnos correctly?

    1Gen-Tundra
    OK Guys, I need your help. I have a 2001 Tundra with 215K miles; I'm the original owner and I'm a lady! I've taken the truck to several different mechanics and I cannot get a straight answer about this code; they simply want to replace the catalytic converter. Also, I've been told to go to a...
  11. P0420 on 2003 V8 SR5 4x4 Tundra

    Intake and Exhaust
    My engine light was going on and off periodically, then finally stayed on. I had the muffler replaced this past weekend because of a hole in the top. While it was at the shop, the technician pulled a P0420 code and reset it. Two days later the light came back on so I took my truck to AutoZone...
  12. 2 Cats in 1?!?

    1Gen-Tacoma
    Just had a really fun day getting my 1998 2.7L 4 cyl 4wd tacoma smogged. It passed the emissions easily, but the test center failed me because the sticker under the hood is saying that it has 2 catalytic converters ("twc+twc") when it only has one. "Comprehensive visual inspection: failed"...
  13. Catalytic Converter Replace Suggestion (2001 4cyl)

    Highlander
    I feel like an outcast... I cannot find any information on how or where to get a bolt-on (not weld on) cat converter for my 2001 4 cyl Highlander. There are a ton of websites with 6cyl models. I found one with an overpriced one for a 4cyl version. My Haynes manual is highly lacking in explaining...
  14. Anyone had a problem with the air pumps for the catalytic converters

    Tundra
    Last week I was driving to the store and suddenly the "check engine" light came on and the truck went into the "limp home" mode which reduces the power. I immediatly took it to the dealer and the code showed that it was an airpump failure. There are two of them and they pump high volumes of...
