Why are you guys removing your cats anyways. 1 you remove all the backpressure which you need. Sure you will get more power but you are seriousely going to impact your fuel economy which is why most of us bought this car in the first place? Second for the slight power you are going to achive which could be only 5hp at the most as opposed to doing a midpipe from the cat back. You are going to cause an extreme amount of polution. As well as mess up egr function. Not to mention how loud it is going to be. So now if you dont like this sound you will have to choose to have a restrictive muffler to muffle the sound which you could just have a nice open muffler with a cat since a cat muffles sound more than your muffler does.
Also I know in california check engine light is automatic smog failure. Not to mention it would automatically fail anyways since you have no cat.
Unless someone can prove me wrong and have thier vehicle smoged without any cats on it would be interesting to see how much emissions our little engines produce. We do have 2 cats though and its not a zero emission vehicle even with those 2 cats. HC is going to be low probally but it probally has a problem with nox
