  2. Eclipse Performance
    Im thinking about gutting my cats, since rre doesnt make their headers anymore, i could order rpw headers but since they are from australia, shipping costs might be absurd. My one question before gutting my cats is if it will pass emissions tests, i will only gut the precats, put spacers on the...

    Hello everyone, I own a 2007 Mitsubishi Eclipse GT and I've had the dreaded O2 sensor codes for as long as I can remember. Just the past weekend, I decided to gut out my pre-cats and install O2 spacers for the oxygen sensors (All 4). I was hoping that the codes would finally disappear but sadly...

    Hey everyone. I just picked up a 2006 GT with 60k miles for free from my mother in law because the cats are bad in it. I’ve been looking for catless headers but not having much luck. I tried RREs website and nothing. Just wanted to see if anyone had a used set for sale or knew where I could pick...
  10. 4G Eclipse GS/SE Specific
    Hey everyone! My son's 06 Eclipse 2.4L died last night on the highway. His CEL gave the codes of P0421 & P0431 as well as P0102. I understand that the codes mean that the cats are bad but the P0102 was for the MAF. The car will start up but will die immediately without feathering the gas...

  14. Problem Reports
    I have an 07 GT Spyder with 122K miles. It's my DD and she still purrs like a tiger. I got these error codes last week while driving back from work. I read the codes after I got home, and hoping it was a 1 off I cleared the codes and the SES light stayed off for about a week. Now the codes are...
  15. GT
    Hey guys, so I have an auto GT, and currently, all I have performance-wise is a 3 inch exhaust from the cats back (no resonator, no muffler, no third cat). Anyways, I love my car, but I wanna get a little more power. I saw this turbo on Ebay that says its specified for our cars. Its by...
  16. Eclipse Performance
    What’s up fellow 4G’ers, I’m looking to play around with my exhaust system again. As some of you know I modified my stock pipe to make it a center exhaust. I currently am running the stock manifold with cats and OEM resonator, but am about to soon install my ceramic coated RRE headers (ive...

    Hi everybody, I've searched the forum for this specifically and I could not find anything on this, so I figured I'd post a question about it. Recently I've purchased an A/M Header w/integrated cats; replaced Bank 1 Sensor 1 O2 Sensor, and managed to reset all codes after logging necessary...

    I do not own an Eclipse but have been looking at a 2009 Eclipse GT for a while and want it bad. Have just not had a chance to go look at it or drive it....Any way a little about me married, 4 cats, bills and a job the American way. This maybe off topic but does this car have a chain or belt?
  20. Mid-Atlantic
    I am looking for place/someone with garage or setup to properly gut my header cats and install O2 sensor spacers. I have the dreaded warm-up cat failing code and I'm not wasting money on another one (once changed under recall). And I'd like to pick up some performance while looking stock for...
