  2. 4G Eclipse GS/SE Specific
    So I've been debating whether or not to buy these RRE headers, i already have my pre-cats gutted out. But I'm looking for more power. Now I've heard that there's not very much of a difference in the two, I'm more of just looking for a second opinion and any advice on the subject. Thanks.

  6. 4G Eclipse GT/SE Specific
    So I'm throwing a code and I've done my research on what could be wrong. It could either be the pre cats or an O2 sensor. The pre cat failure seems to be premature since I'm only at 87,000 miles.has anybody encountered this code and fixed it ? If it is a O2 sensor which one do I buy to replace...
  7. 4G Eclipse GS/SE Specific
    I just bought a RS style carbon fiber muffler for my eclipse. My plans are to build a custom exhaust. I did use the search bar and read the post on exhaust faqs. My next install is a CAI and OBX headers, but what kind of pipe do i need to buy to run under the car to my muffler, and do I need to...
  8. 4G Eclipse GT/SE Specific
    I wanted to ask opinions on real dual custom exhaust for the 2011-2012 GT's. I just bought a 2011 and have my old GS setup catback from magnaflow. I bought the same setup but with the part numbers from magnaflow it only cost me a little over 200.00 so now I have two mufflers, 2 resonators, 2...

  10. 4G Eclipse GS/SE Specific
    Michael (eosrebel) came by this weekend to help me gut the pre-cats. Once we wiggled all the sticking bolts loose and gently convinced the O2 sensors to come out, we removed all the packing and put it back in to test. Unfortunately there were a few nasty exhaust holes and it had a very nasty...

  14. Automotive For Sale/Wanted
    I am in need of a set of California legal exhaust manifolds with working cats. Lower the mileage the better. They need to be unmodified and working as I will have to pass smog this March. So If are parting out your car and can help me out please let me know. Thanks, Ryan.
  15. 2006-2012 Eclipse (General 4G)
    I have a rattle that I'm fairly sure is coming from my high flow cat so I want to go ahead and straight pipe it. My buddy does exhaust work and says that you have to "flare" both ends and doesn't have the ability to do that. Is this true for our cars? Because he is surprised on the fact that we...
  16. 2006-2012 Eclipse (General 4G)
    The jist of this post: If you live in Washington state, you can pass the emissions test while throwing the code P0431 (and presumably P0421). (My exhaust is stock with all 3 cats) The wordy version: My cars been throwing P0431 for the last year and I've been procrastinating taking it into the...
