just a ? do i need to do anything about my 02 sensor and which one is beter ?

haysdb

The O2 sensors should be fine. I had to fuss around with mine a little, to get rid of a couple of Check Engine errors, but I seem to be in a very small minority who have experienced this particular issue. If you do, we can help you through it.

I can't say which one is "better", but I am pleased with the fitment of the Warpspeed pipe. Budget is the other "affordable" option, and the other pipe I considered. I just received and installed mine two weeks ago.

Haysdb, do you feel a noticable difference?

haysdb

I believe I do, but I have no dyno readings or 1/4 mile times to back me up. In combination with an intake, it sure SOUNDS like I have more power, so it's difficult to be truly objective.

I have a custom Cattman, but I've heard budget is the best bang for buck with the same quality. I do not, however, recommend Stillen y's. Bees in a can noise, had to get rid of mine. Hope this helps.

How does the Cattman ypipe gain feel? Significant? Low or high RPM range?

Since we're talking about ypipes... anyone has the Cattman header/ypipe combo? I know it's supposed to be 18-19 hp at the wheels but how does the butt dyno register? Significant?

i'm concerned of it being too loud.

I have a budget pipe with the stock muffler. Also I have a stock intake. Your intake will be louder at all levels than your exhaust. Don't worry about the noise from adding a y-pipe.

haysdb

I agree with what PLUMMAXSE just said, at least to a point. The intake noise will drown out any sound from the exhaust, but only when you really get on the throttle. At part throttle, I don't hear any intake noise. Driving "easy", I hear neither the intake nor the y-pipe. And then again, my hearing isn't necessarily that accute!
