Turns out I've got an exhaust leak right where my header meets my "collector". Its basically the pipe that has the bungs for the 02 sensors. The bracket came loose because all 3 bolts fell out and that caused the pipes to separate enough to give me a leak. I think this is the reason for loss of power and shaking at certain rpms.

Here's a pic!

 

Are those the SS OBX? They look rough

 

They are cheap stainless and have a lot of iron content. My steel Pacesetters look better.

 

Yup they are rough. But I also live in the salt belt.

 

Also the reason for the p171 & p174 codes.

 

Yup. So I'm calling my exhaust shop tomorrow to make an appt with them. Hopefully she runs like a top after this is fixed.

My buddy told me to just chop off all the pipes and run open headers to save the money but I don't think I'll be able to stand the noise lol

 

I know I wouldn't lol just sitting in my truck at idle with my setup that was pretty much open headers was enough to give you a headache.

 

that's a shame man
Sounds like pacesetters or Dynatechs for me

 

 

are those bigger expy hubs?
Lol my eyes are playing tricks that one looks bigger in each picture
