Came with all necessary parts and gaskets. Catback went on first, about an hour and a half with me and another guy doing it. The downpipe took only an hour. No CEL yet either šŸ˜ƒ A lift is a must though if you dont wanna fight and fight. > > What makes you say that? The car runs quite rich from the factory. By allowing more airflow with intake and turboback it makes the car have more power, but SAFELY. Did lots of reading. A tune is the best thing for the car, though, BECAUSE it runs so rich, but Iā€™m far from grenade status. The AccessPort is something plenty of EVO X guys do. It happens to be a ā€œreal tuneā€ because the use can install preset settings OR map their own settings. > > If I happen to go with cams or a bigger turbo/injectors blah blah blah then Iā€™d get a dyno tune for sure. So the car runs rich everywhere over the power band, at every single load level, at any rpm? You did all the math to calculate how much more air is being let it everywhere over the power band, at every single load level, at any rpm?? You calculated how all that air would react with the ā€œrichā€ stock tune everywhere over the entire power band, at every single load level, at any rpm?? You calculated how the decreased back pressure would affect the above? You calculated how the millions of things I left out come into play? Did you do any logging whatsoever? You can tune the with your mind bro? I didnā€™t think so. A cat back is one thing, but an intake and downpipe as well is a ticking time bomb. Get a tune ASAP or take all the parts off until you can afford a tune. 500 dollar tune or 9000 dollar engine. Your choice. --- _[View the full topic](https://forums.speedlife.net/t/erngottis-08-evox/255807)._
