I installed a off road h pipe. Now there is a noise that I am guessing is from the vaccum line that goes to the sensor coming off the stock hpipe. How do I get it to go away. Doesn't do it at idle just when I'm getting on the gas.

Do you mean exhaust leak?

Guess it could be... I'm not sure it's sound like it's on the throttle body side

Did you reattach the smog pipe that goes from your smog pump to your h-pipe? Or o2 sensors? That would give you a pretty loud exhaust leak.

No I didn't reattach to the smog pump...

Plug it or reattach the pipe. It sounds like crap and robs performance

My new hpipe doesn't have a spot to plug it back into

So if my hpipe doesn't have a spot for it what can I do so it's not so loud...?

If there isn't a provision for the smog pipe then the loudness isn't the issue there. I would check to make sure you don't have an exhaust leak elsewhere. Use a smoke detector around your headers, collector, mid pipe to mufflers to find where the leak is.

There's a line coming off the smog pump and it tees. On line goes around the engine and the other is suppose to plug into the hpipe but I don't have that one hooked up so it's pumping air out of it.

You have to delete smog pump now.its just pumping air.you can bypass it with a shorter belt.do a Google search or maybe someone can post the size.good luck.

Yea,even with stock pulleys I had to get a few different belts.nothing a few trips to the parts store can't fix.
