    Hi guys. I'm going to get rid of my exhaust headers cats. First I was thinking about gutting cats. But according to a lot of responses it is not the best option. Unfortunately I can't find RRE or OBX headers in my country so I decided to try Lacer 2004 Ralliart headers, they look pretty nice and...
  2. 4G Eclipse GT/SE Specific
    I have a 2011 GT with dual exhaust tips and I've seen several bolt-on kits for the GT V6 but they all seem to only be for the single-tip exhaust options. Does anyone know if a bolt on option for this exists and is available? Or (more likely probably) will I have to go with custom exhaust if I...

    Would it be worth it to go with that setup on an 09 GT Auto? Looking to increase more power but RRE doesn’t seem to be making any headers soon (I have emailed them but still no answer) Or should I just stick with OBX headers even though a lot of people say they will just cause problems. Thanks!

    Hey everyone! New to the forum. Bought an 07 Eclipse GT about 8 months ago and it's started to give me issues. It's currently throwing a P0421 for the warm up cat. Unfortunately I'm in PA, so any exhaust related codes will automatically fail emissions. I know about the anti-fouler trick, but I'd...

    Hello everyone, have had my eclipse for a few months now and I've waited a bit to be sure that I love the car before I mod it (I instantly knew I liked it the first time I got to drive it) I have a few questions when it comes to mods. -Power/sound mods: I looked through the forum and found...

  9. 4G Eclipse GS/SE Specific
    So I just bought a 2007 gs eclipse and it’s only got 90k miles on it. There aren’t any modifications on it right now but I plan on doing some of my own things to the car. I’m also pretty new to car modifications so I might be using this website a lot. This first thing I plan on doing to my...

    hey guys! i've got the 2.4L/4cyl eclipse and i'm looking to get the exhaust sounding a little better. i'm running a straight pipe with the stock resonator (bought it like this; pretty sure the cat is up there too) and i know this engine's got at least a little bit more sound potential than what...
  12. Problem Reports
    Hi Need some advice. 2007 2.4l 275K miles I've owned the car since 2010, 33K miles. I've had great luck with this car, no major issues ever, except for the brakes randomly going out on me about 2 years ago-which was fixed with a recall. Not sure if any of this is related. I screwed up...
  13. 4G Eclipse GT/SE Specific
    So I was driving today on the freeway and I was in second gear to overtake a big semi, but I didn’t realize I had to shift! (stupid me) so the the tach bounced off the limiter and I just hear my exhaust go “pop pop pop” and the car shut off. I coasted into a gas station, tried to start it up...
  14. Forced Induction & Nitrous
    I have been looking around and it seems that RRM makes turbo kits for the 2000s lancer ralliart that shares the same engine, 4g69, with us. They also make performance parts for the 4g69, like port and polished intake manifold, and turbo exhaust manifolds, that in the site, they say it fits the...

    Hey new comer here, i just got an eclipse 07 for free, and its basically mint too at 57k miles, a good deal in my opinion, and i just wanted to know if i can get this little slug to 200hp, or atleast like 180whp or something because imo its pretty slow, bordering prius power at like 130whp, but...
  17. 2006-2012 Eclipse (General 4G)
    I've been thinking about installing a new axle-back for my 2011 Eclipse GS Sport. I've looked at recommendations from various posts on club4g but most people recommend Road Race Engineering and they only have the "Road Race Axle Back Exhaust 2006-2008", not anything for a 2011 GS dual exhaust...
  18. 4G Eclipse GS/SE Specific
    A while back I changed my spark plugs for the first time and noticed some oil in cylinders #2 and #3. It wasn't an alarming amount and it was mostly up by the top of the plug and not at the bottom, so after a chat with my mechanic friend I decided it wasn't an emergency. I bought the valve cover...

  20. 4G Eclipse GT/SE Specific
    I have looked all over the site and have researched online with no luck. My 2011 GT has dual exhaust. I would like a louder exhaust but prefer bolt on and would love to be able to hear what it would sound like before I purchase. I want it to be louder outside the car but not inside. Although...
