Default obx headers

Anybody tried the obx headers? Any fitment issues or anything?

I have some on my CTS V and dont have any complaints.

Thanks.

I have heard they fit fine. The y pipe is what people have problems with. A lot of people have a custom one made.

I love my OBX's. No fitment issues at all, except for the y pipe like said above.

Some people don't like where they put the o2 sensor bungs, you need to buy harness extenders. Some people splice more wire in but I wouldn't do that personally wouldnt do that. The other issue some have is clearance on the passenger side. They had to dent in the body to get some clearance. For the price, these are minor issues. The one other complaint with the y-pipe is that it is 2.5 pipe. Some argue that it's not big enough. I think when I get headers, I will give these a try. I have no plans of building some 500hp engine, so these will do fine.

I installed a set on a buddies TBSS and had no fitment issues. The o2 sensors are at the bottom of the merge but he has run his like this for almost 2 years with no issues. O2's still respond quickly. The hardware to secure the ypipe to the collector sucks. I would replace those if you can. He made 500+hp with the 2.5'' ypipe too.
