    It all depends on how strict your state is. You can get a catted-Y pipe with your headers and then get the computer tuned to delete the rear 02's and it'll pass a visual inspection. The hydrocarbon release will be higher than stock simply because you're flowing more exhaust more freely and high flow cats don't burn up the unspent fuel as well simply because the exhaust is flowing out more quickly than stock. If you're state uses a sniffer and expects your car to be within a range/percenteage of stock you might have problems no matter what you do. I've heard of some pulling a plug off a fuel injector to get past emissions, but I've never tried it myself since we don't have inspection out in the county.

    Stay away from slp, well at least for the headers, y pipe, and stuff. I have a obx racing header/high flow cat/y combo it came all together for only $695.00 plus it's stainless steel. But Texas Speed sells a pacesetter and catted y combo that is a pretty good price too which I would have gotten but I wanted stainless steel.

    Well for the texas speed kit go to texas-speedand for obx kits i went on ebay and searched obx ls1 headers. Just make sure for the obx stuff on ebay that it says it comes with high flow cats otherwise they will be resonators even though they look the same and the price should be around 675-695 if it is in the $499 or close to that they most likely come without cats.

    Yea I feel a significant power increase. I would put up a video of it for you to see but it's in the shop right now getting a misfire fixed. When I get it back this week I will put a video up. But it definitely sounds really mean
