I have taken out the Catillic converter and the muffler out of my truck. As soon as i idle my exhaust sounds like an airplane. How do i get rid of this? Sounds like a vacuum.


I also using the edge programmer this thing is amazing. How will this affect the transmission?

That's what mufflers are for. How did you expect it to sound?

I welded the cat into the 4' pipe with a free flow muffler and it sound good. the vac noise is down 70% i love it sound good
